75th Anniversary Issue

TIME was first published on March 3, 1923 as a newsmagazine which summarized and organized the news so that "busy men" could stay informed. Here are some articles to help you learn more about the history of TIME and how it has evolved since its founding more than 80 years ago. The evening that the first issue went to press (and many press nights thereafter), the entire full-time staff got into a taxicab, carrying the entire editorial reference library (Who's Who, World Almanac, Congressional Directory) and drove to the printers on Manhattan's 11th Avenue.  

One of the hallmarks of the newsmagazine format that Henry Luce and Briton Hadden created in 1923 was a penchant for telling stories through people. Carlyle defined history as "the biography of great men." Similarly, Luce and Hadden's TIME showed that journalism, the rough draft of history, could illuminate momentous events by profiling the gifted and powerful personalities who helped shape them. Nowhere more so than in TIME's selection of a Person of the Year, which has been a highlight since 1927. These iconic figures--statesmen, visionaries, tyrants, unexpected heroes like New York City Mayor RUDY GIULIANI--were singled out because they put a stamp on their world and expressed the great themes of their times. The vivid fascination and significance they represent can be appreciated in a multimedia exhibition, "TIME's Person of the Year at 75," which has traveled to three U.S. cities in the past year and is on view in Chicago through Jan. 5. Open the following pages for a sampling of the absorbing, inspiring and provocative figures featured in the exhibition.
1928 WALTER P. CHRYSLER The son of a Kansas locomotive engineer, Chrysler learned about cars by taking them apart and reassembling them. He showed the same ability with companies. By the end of 1928 his innovative Chrysler Motors was turning out not only its namesake models but also Plymouths, Dodges and DeSotos, mounting a challenge to automotive giants Ford and General Motors. Chrysler, wrote TIME, "had become one of the chief U.S. industrialists." But he was not through building. In this same year he announced plans for the 77-story Chrysler Building, whose graceful Art Deco structure remains one of the signature profiles of the Manhattan skyline.
1937 GEN. AND MME. CHIANG KAI-SHEK He was the leader who had unified most of China under a reformist government. She was a daughter of the eminent, Western-oriented Soong family who became his effective propagandist in the U.S. Though they had been forced to flee the Japanese invasion in 1937, TIME saluted them for forging a Chinese "national consciousness.
1938 ADOLF HITLER Hitler was the first malign figure to be selected as POY, and his evil only grew during the next several years. Hitler's ruthless domination of Europe was, said TIME, "the greatest threatening force that the democratic, freedom-loving world faces today." The 1938 Munich pact confirmed it: he won a hands-off promise from Britain and France, and the stage was set for his pursuit of World War II.
1947 GEORGE C. MARSHALL Named POY first as a man of war--in 1943, when he was Chief of Staff of the Army--Marshall was chosen again as a man of peace: the Secretary of State who conceived the Marshall Plan, which promised to underwrite the economic recovery of postwar Europe's democracies. Through his bold scheme, said TIME, "the U.S. people, not quite realizing the full import of their act ... took upon their shoulders the leadership of the world."

How are ants able to move/pull objects that are heavier than the insect?

Can we imagine carrying ten-time heavier objects than our body weight? It may be possible for the ‘ super-man', but not for an ordinary man. However, ants could carry or pull objects weighing several folds heavier than their own body weights.
Do ants possess stronger muscles that enable them to produce more strength than humans? The answer is ‘NO', according to Sir Vincent Brian Wigglesworth, the ‘Father of Insect Physiology' who compared and found no differences between the muscle force (per unit area) of insects and vertebrates. Then what enables the ants to carry heavier objects is their relatively smaller body size.
According to the square – cube law, when an object undergoes a proportional increase in size, its new volume is proportional to the cube of the multiplier and its new surface area is proportional to the square of the multiplier. When an animal grows in length (or height), the volume increases in cube but the cross sectional area of its muscles increases only in square.
Mass is the amount of matter in an object, and hence the (cubic) increase in volume tends to increase the body mass significantly, whereas the cross-sectional area of the muscles increases in a much slower rate (only in square). Hence, these cross sectional areas of muscles have to support relatively more mass and thus larger animals like humans need to put most of the muscles in use to carry their own mass.
In other words, larger animals have to carry their own weight, besides the heavier objects; so they are able to carry only slightly heavier objects. However, because of the smaller body size, the body mass of ants is much lower and hence they put fewer muscles into use to carry this body mass. Thus, ants could use more muscles to carry bigger loads than their own mass, which not only applies to ants, but also holds good for most of the insects. However, since ants are quite abundant in human habitats, we frequently seeing them carrying big

Tomb of King Tut Discovered 1922


Though several of the foremost excavators over the past century had declared there was nothing left to find in the Valley of the Kings, Howard Carter and his sponsor, Lord Carnarvon, spent a number of years and a lot of money searching for a tomb they weren't sure existed. In November 1922, they found it. Carter had discovered not just an unknown ancient Egyptian tomb, but one that had lain nearly undisturbed for over 3,000 years. What lay within astounded the world.

Uncertainty
Work feverishly continued on the afternoon of November 4th through the following morning. By late afternoon on November 5th, 12 stairs (leading downwards) were revealed; and in front of them, stood the upper portion of a blocked entrance. Carter searched the plastered door for a name but of the seals that could be read, he found only the impressions of the royal necropolis. Carter was extremely excited:
The design was certainly of the Eighteenth Dynasty. Could it be the tomb of a noble buried here by royal consent? Was it a royal cache, a hiding-place to which a mummy and its equipment had been removed for safety? Or was it actually the tomb of the king for whom I had spent so many years in search?2
To protect the find, Carter had his workmen fill in the stairs, covering them so that none were showing. While several of Carter's most trusted workmen stood guard, Carter left to make preparations. The first of which was contacting Lord Carnarvon in England to share the news of the find. On November 6th, two days after finding the first step, Carter sent a cable: "At last have made wonderful discovery in Valley; a magnificent tomb with seals intact; re-covered same for your arrival; congratulations."3
It was nearly three weeks after finding the first step that Carter was able to proceed. On November 23rd, Lord Carnarvon and his daughter, Lady Evelyn Herbert, arrived in Luxor. The following day, the workers had again cleared the staircase, now exposing all 16 of its steps and the full face of the sealed doorway. Now Carter found what he could not see before, since the bottom of the doorway had still been covered with rubble - there were several seals on the bottom of the door with Tutankhamun's name on them.
Now that the door was fully exposed, they also noticed that the upper left of the doorway had been broken through, presumably by tomb robbers, and resealed. The tomb was not intact; yet the fact that the tomb had been resealed showed that the tomb had not been emptied.

1928 - Penicillin Discovered


Penicillin is one of the earliest discovered and widely used antibiotic agents, derived from the Penicillium mold. Antibiotics are natural substances that are released by bacteria and fungi into the their environment, as a means of inhibiting other organisms - it is chemical warfare on a microscopic scale.

  • Alexander Fleming
  • born August. 6, 1881 , Darvel, Scotland
  • died March 11, 1955 , London, England
In 1928, Sir Alexander Fleming observed that colonies of the bacterium Staphylococcus aureus could be destroyed by the mold Penicillium notatum, proving that there was an antibacterial agent there in principle. This principle later lead to medicines that could kill certain types of disease-causing bacteria inside the body.
At the time, however, the importance of Alexander Fleming's discovery was not known. Use of penicillin did not begin until the 1940s when Howard Florey and Ernst Chain isolated the active ingredient and developed a powdery form of the medicine.

History of Penicillin

Originally noticed by a French medical student, Ernest Duchesne, in 1896.
 Penicillin was re-discovered by bacteriologist Alexander Fleming working at St. Mary's Hospital in London in 1928. He observed that a plate culture of Staphylococcus had been contaminated by a blue-green mold and that colonies of bacteria adjacent to the mold were being dissolved. Curious, Alexander Fleming grew the mold in a pure culture and found that it produced a substance that killed a number of disease-causing bacteria. Naming the substance penicillin, Dr. Fleming in 1929 published the results of his investigations, noting that his discovery might have therapeutic value if it could be produced in quantity.

Hodgkin used x-rays to find the structural layouts of atoms and the overall molecular shape of over 100 molecules including penicillin. Dorothy's discovery of the molecular layout of penicillin helped lead scientists to develop other antibiotics.

It was not until 1939 that Dr. Howard Florey, a future Nobel Laureate, and three colleagues at Oxford University began intensive research and were able to demonstrate penicillin's ability to kill infectious bacteria. As the war with Germany continued to drain industrial and government resources, the British scientists could not produce the quantities of penicillin needed for clinical trials on humans and turned to the United States for help. They were quickly referred to the Peoria Lab where scientists were already working on fermentation methods to increase the growth rate of fungal cultures. One July 9, 1941, Howard Florey and Norman Heatley, Oxford University Scientists came to the U.S. with a small but valuable package containing a small amount of penicillin to begin work.
Pumping air into deep vats containing corn steep liquor (a non-alcoholic by-product of the wet milling process) and the addition of other key ingredients was shown to produce faster growth and larger amounts of penicillin than the previous surface-growth method. Ironically, after a worldwide search, it was a strain of penicillin from a moldy cantaloupe in a Peoria market that was found and improved to produce the largest amount of penicillin when grown in the deep vat, submerged conditions.

By November 26, 1941, Andrew J. Moyer, the lab's expert on the nutrition of molds, had succeeded, with the assistance of Dr. Heatley, in increasing the yields of penicillin 10 times. In 1943, the required clinical trials were performed and penicillin was shown to be the most effective antibacterial agent to date. Penicillin production was quickly scaled up and available in quantity to treat Allied soldiers wounded on D-Day. As production was increased, the price dropped from nearly priceless in 1940, to $20 per dose in July 1943, to $0.55 per dose by 1946.
As a result of their work, two members of the British group were awarded the Nobel Prize. Dr. Andrew J. Moyer from the Peoria Lab was inducted into the Inventors Hall of Fame and both the British and Peoria Laboratories were designated as International Historic Chemical Landmarks.

Andrew J Moyer Patent

On May 25, 1948, Andrew J Moyer was granted a patent for a method of the mass production of penicillin.

Resistance to Penicillin

Four years after drug companies began mass-producing penicillin in 1943, microbes began appearing that could resist it.
The first bug to battle penicillin was Staphylococcus aureus. This bacterium is often a harmless passenger in the human body, but it can cause illness, such as pneumonia or toxic shock syndrome, when it overgrows or produces a toxin.
(Gr. anti, "against"; bios, "life") An antibiotic is a chemical substance produced by one organism that is destructive to another. The word antibiotic came from the word antibiosis a term coined in 1889 by Louis Pasteur's pupil Paul Vuillemin which means a process by which life could be used to destroy life.

Henry Ford Changes the World, 1908


Henry Ford Changes the World, 1908


At the beginning of the 20th century the automobile was a plaything for the rich. Most models were complicated machines that required a chauffer conversant with its individual mechanical nuances to drive it. Henry Ford was determined to build a simple, reliable and affordable car; a car the average American worker could afford. Out of this determination came the Model T and the assembly line - two innovations that revolutionized American society and molded the world we live in today.
Henry Ford did not invent the car; he produced an automobile that was within the economic reach of the average American. While other manufacturers were content to target a market of the well-to-do, Ford developed a design and a method of manufacture that

the Quadricycle, which he
built in 1896
steadily reduced the cost of the Model T. Instead of pocketing the profits; Ford lowered the price of his car. As a result, Ford Motors sold more cars and steadily increased its earnings - transforming the automobile from a luxury toy to a mainstay of American society.
The Model T made its debut in 1908 with a purchase price of $825.00. Over ten thousand were sold in its first year, establishing a new record. Four years later the price dropped to $575.00 and sales soared. By 1914, Ford could claim a 48% share of the automobile market.
Central to Ford's ability to produce an affordable car was the development of the assembly line that increased the efficiency of manufacture and decreased its cost. Ford did not conceive the concept, he perfected it. Prior to the introduction of the assembly line, cars were individually crafted by teams of skilled workmen - a slow and expensive procedure. The assembly line reversed the process of automobile manufacture. Instead of workers going to the car, the car came to the worker who performed the same task of assembly over and over again. With the introduction and perfection of the process, Ford was able to reduce the assembly time of a Model T from twelve and a half hours to less than six hours.
Developing the Model T
The Ford Motor Company manufactured its first car - the Model A - in 1903. By 1906, the Model N was in production but Ford had not yet achieved his goal of producing a simple, affordable car. He would accomplish this with the Model T. Charles Sorensen - who had joined Henry Ford two years earlier - describes how Ford had him set up a secret room where design of the new car would be carried out:
"Early one morning in the winter of 1906-7, Henry Ford dropped in at the pattern department of the Piquette Avenue plant to see me. 'Come with me, Charlie,' he said, 'I want to show you something.'
I followed him to the third floor and its north end, which was not fully occupied for assembly work. He looked about and said, 'Charlie, I'd like to have a room finished off right here in this space. Put up a wall with a door in big enough to run a car in and out. Get a good lock for the door, and when you're ready, we'll have Joe Galamb come up in here. We're going to start a completely new job.'
The room he had in mind became the maternity ward for Model T.
It took only a few days to block off the little room on the third floor back of the Piquette Avenue plant and to set up a few simple power tools and Joe Galamb's two blackboards. The blackboards were a good idea. They gave a king-sized drawing which, when all initial refinements had been made, could be photographed for two purposes: as a protection against patent suits attempting to prove prior claim to originality and as a substitute for blueprints. A little more than a year later Model T, the product of that cluttered little room, was announced to the world. But another half year passed before the first Model T was ready for what had already become a clamorous market...
The summer before, Mr. Ford told me to block off the experimental room for Joe Galamb, a momentous event occurred which would affect the entire automotive industry. The first heat of vanadium steel in the country was poured at the United Steel Company's plant in Canton, Ohio.
Early that year we had several visits from J. Kent Smith, a noted English metallurgist from a country which had been in the forefront of steel development...

Ford, Wills, and I listened to him and examined his data. We had already read about this English vanadium steel. It had a tensile strength nearly three times that of steels we were using, but we'd never seen it. Smith demonstrated its toughness and showed that despite its strength it could be machined more easily than plain steel. Immediately Mr. Ford sensed the great possibilities of this shock-resisting steel. 'Charlie,' he said to me after Smith left, 'this means entirely new design requirements, and we can get a better, lighter, and cheaper car as a result of it.'
It was the great common sense that Mr. Ford could apply to new ideas and his ability to simplify seemingly complicated problems that made him the pioneer he was. This demonstration of vanadium steel was the deciding point for him to begin the experimental work that resulted in Model T...
Actually it took four years and more to develop Model T. Previous models were the guinea pigs, one might say, for experimentation and development of a car which would realize Henry Ford's dream of a car which anyone could afford to buy, which anyone could drive anywhere, and which almost anyone could keep in repair. Many of the world's greatest mechanical discoveries were accidents in the course of other experimentation. Not so Model T, which ushered in the motor transport age and set off a chain reaction of machine production now known as automation. All our experimentation at Ford in the early days was toward a fixed and, then wildly fantastic goal.
By March, 1908, we were ready to announce Model T, but not to produce it, On October 1 of that year the first car was introduced to the public. From Joe Galamb's little room on the third floor had come a revolutionary vehicle. In the next eighteen years, out of Piquette Avenue, Highland Park, River Rouge, and from assembly plants all over the United States came 15,000,000 more."
Birth of the Assembly Line
A few months later- in July 1908 - Sorensen and a plant foreman spent their days off developing the basics of the Assembly Line:
"What was worked out at Ford was the practice of moving the work from one worker to another until it became a complete unit, then arranging the flow of these units at the right time and the right place to a moving final assembly line from which came a finished product. Regardless of earlier uses of some of these principles, the direct line of succession of mass production and its intensification into automation stems directly from what we worked out at Ford Motor Company between 1908 and 1913...
As may be imagined, the job of putting the car together was a simpler one than handling the materials that had to be brought to 

The old fashioned way - limousines are

it. Charlie Lewis, the youngest and most aggressive of our assembly foremen, and I tackled this problem. We gradually worked it out by bringing up only what we termed the fast-moving materials. The main bulky parts, like engines and axles, needed a lot of room. To give them that space, we left the smaller, more compact, light-handling material in a storage building on the northwest comer of the grounds. Then we arranged with the stock department to bring up at regular hours such divisions of material as we had marked out and packaged.
This simplification of handling cleaned things up materially. But at best, I did not like it. It was then that the idea occurred to me that assembly would be easier, simpler, and faster if we moved the chassis along, beginning at one end of the plant with a frame and adding the axles and the wheels; then moving it past the stockroom, instead of moving the stockroom to the chassis. I had Lewis arrange the materials on the floor so that what was needed at the start of assembly would be at that end of the building and the other parts would be along the line as we moved the chassis along. We spent every Sunday during July planning this. Then one Sunday morning, after the stock was laid out in this fashion, Lewis and I and a couple of helpers put together the first car, I'm sure, that was ever built on a moving line.
We did this simply by putting the frame on skids, hitching a towrope to the front end and pulling the frame along until axles and wheels were put on. Then we rolled the chassis along in notches to prove what could be done. While demonstrating this moving line, we worked on some of the subassemblies, such as completing a radiator with all its hose fittings so that we could place it very quickly on the chassis. We also did this with the dash and mounted the steering gear and the spark coil."
Implementation
The basics of the Assembly Line had been established but it would take another five years for the concept to be implemented. Implementation would await construction of the new Highland Park plant which was purpose-built to incorporate the assembly line. The process began at the top floor of the four-story building where the engine was assembled and progressed level by level to the ground floor where the body was attached to the chassis.

"By August, 1913, all links in the chain of moving assembly lines were complete except the last and most spectacular one - the one we had first experimented with one Sunday morning just five years before. Again a towrope was hitched to a chassis, this time pulled by a capstan. Each part was attached to the moving chassis in order, from axles at the beginning to bodies at the end of the line. Some parts took longer to attach than others; so, to keep an even pull on the towrope, there must be differently spaced intervals between delivery of the parts along the line. This called for patient timing and rearrangement until the flow of parts and the speed and intervals along the assembly line meshed into a perfectly synchronized operation throughout all stages of production. Before the end of the year a power-driven assembly line was in operation, and New Year's saw three more installed. Ford mass production and a new era in industrial history had begun"
