Polaroid

In 1932, he established the Land-Wheelwright Laboratories together with his Harvard physics professor, George Wheelwright III, to commercialize his polarizing technology. Wheelwright came from a family of financial means and agreed to fund the company. After a few early successes developing polarizing filters for sunglasses and photographic filters, Land obtained funding from a series of Wall Street investors for further expansion.^[6]: 69

The company was renamed the Polaroid Corporation in 1937.^[13][10]

Land further developed and produced the sheet polarizers under the Polaroid trademark. Although the initial major application was for sunglasses and scientific work, it quickly found many additional applications: for color animation in the Wurlitzer 850 Peacock jukebox of 1942, for glasses in full-color stereoscopic (3-D) movies, to control brightness of light through a window, a necessary component of all LCDs, and many more.

During World War II, he worked on military tasks, which included developing dark-adaptation goggles, target finders, the first passively guided smart bombs, and a special stereoscopic viewing system called the Vectograph, co-invented with Czech refugee Joseph Mahler, which revealed camouflaged enemy positions in aerial photography. With all this, he was also a consultant to the National Research Defense Committee which focused its efforts on non-governmental scientific research.^[10]

In a vacation to Santa Fe, New Mexico, with his three-year-old eldest daughter, Jennifer, he took a picture of her. After she asked why she could not see the picture her father just took of her, within an hour he already had the idea for an instant film camera. His patent attorney, Donald Brown, was also there at the time visiting Santa Fe and he quickly approached him with this idea and Brown agreed on the idea.^[14] After this trip, research for the development of this idea began immediately.

A little more than three years later, on February 21, 1947, Land demonstrated an instant camera and associated film to the Optical Society of America.^[15] Called the Land Camera, it was in commercial sale less than two years later. Polaroid originally manufactured sixty units of this first camera. Fifty-seven were put up for sale at the Jordan Marsh department store in Boston before the 1948 Christmas holiday. Polaroid marketers incorrectly guessed that the camera and film would remain in stock long enough to manufacture a second run based on customer demand. All fifty-seven cameras and all of the film were sold on the first day of demonstrations.

During his time at Polaroid, Land was notorious for his marathon research sessions. When Land conceived of an idea, he would experiment and brainstorm until the problem was solved with no breaks of any kind. He needed to have food brought to him and to be reminded to eat.^[12] He once wore the same clothes for eighteen consecutive days while solving problems with the commercial production of polarizing film.^[12] As the Polaroid company grew, Land had teams of assistants working in shifts at his side. As one team wore out, the next team was brought in to continue the work.

Elkan Blout, a close colleague of Edwin Land at Polaroid, wrote: "What was Land like? Knowing him was a unique experience. He was a true visionary; he saw things differently from other people, which is what led him to the idea of instant photography. He was a brilliant, driven man who did not spare himself and who enjoyed working with equally driven people."^[16]

Contributions to photo intelligence

Beginning in the early years of the Cold War, Land played a major role in the development of photographic reconnaissance and intelligence gathering efforts. Projects included the Genetrix balloon borne cameras, the U-2 program, Corona and Samos photographic satellites, and the Manned Orbiting Laboratory. He was a frequent advisor to President Dwight D. Eisenhower on photographic reconnaissance matters.^[17]

Later years

In the 1950s, James G. Baker, Land, and his team helped design the optics of the revolutionary Lockheed U-2 spy plane. He also contributed to the design of the plane with Kelly Johnson.^[18] Also in this decade, Land first discovered a two-color system for projecting the entire spectrum of hues with only two colors of projecting light (he later found more specifically that one could achieve the same effect using very narrow bands of 579 nm and 599 nm light).^[19] Some of this work was later incorporated in his Retinex theory of color vision.

In 1957, Harvard University awarded him an honorary doctorate, and Edwin H. Land Blvd., a street in Cambridge, Massachusetts, was later named in his memory. The street is at one end of Memorial Drive, in Cambridge, where the Polaroid company headquarters building was located (over a mile west on Memorial Drive from Land Blvd.). Polaroid occupied several buildings in various places in Cambridge.

In the early 1970s, Land attempted to explain the previously known phenomenon of color constancy with his retinex theory. His popular demonstrations of color constancy raised much interest in the concept. He considered his leadership towards the development of integral instant color photography — the SX-70 film and camera — to be his crowning achievement.

Although he led the Polaroid Corporation as a chief executive, Land was a scientist first and foremost, and as such made sure that he performed "an experiment each day". Despite holding no formal degree, employees, friends, and the press respected his scientific accomplishments by calling him Dr. Land. The only exception was The Wall Street Journal, which refused to use that honorific title throughout his lifetime.^[12]

Land often made technical and management decisions based on what he felt was right as both a scientist and a humanist, much to the chagrin of Wall Street and his investors. From the beginning of his professional career, he hired women and trained them to be research scientists. Following the assassination of Martin Luther King Jr. in 1968, he led Polaroid to the forefront of the affirmative action movement.

He had an artistic vision. In his laboratory, he built giant studio cameras the size of bedroom closets that produced large format (20 x 24 inch) prints. He gave photographers free access to these cameras in return for some of the prints they produced.^[20] This practice was continued by the company; the result was the Polaroid Collection. Compiled since the 1970s, the collection grew to between 16,000 and 24,000 photos shot by some of the world's greatest artists and photographers, including Ansel Adams, Chuck Close, Robert Frank and Andy Warhol. The collection, an asset of the Polaroid Corporation, remained intact until 2010 when, in controversial circumstances, it was broken up and put up for sale in lots.^[21]

Land resigned from his role as Presidential Advisor during Nixon's Watergate scandal in 1973. He was one of the names in Nixon's "political opponents" (following the original top 20 enemies)^[22]

Despite the tremendous success of his instant cameras, Land's Polavision instant movie system was a financial disaster,^[23] and he resigned as Chairman of Polaroid on July 27, 1982.^[24] When he retired, he had 535 patents to his name, only surpassed by Thomas Edison and Elihu Thomson. While he was set for retirement years, this did not mean the end of his passion in research and decided to continue with his interest in color vision.^[25] From 1978, he was a regular visitor to the laboratory of Semir Zeki at University College London, to attend Zeki's experiments on color vision. Although they never published together, Land was to design the gelatin filters to accompany the paper on the physiology of color vision published by Zeki in Nature in 1980.^[26] These filters, and especially the long-wave one, were later used to study details of the structure of DNA. Before Land died, Zeki negotiated with the Royal Society to take a page of the Royal Society Fellows Book for Land to sign in the United States, since he was too ill to attend the signing ceremony in London. It was signed at a small private ceremony in Land's home in Cambridge, Mass., attended by his son-in-law; the citations were read by Zeki and Hugh Huxley admitted Land formally to the Society. The other Foreign Member of the Royal Society who also signed the book on the same occasion was Ed Purcell, the discoverer of nuclear magnetic resonance and a friend of Edwin Land. It is reputed that the only other times that the book (or in this case a page of it) of the Royal Society was taken outside its house in London was when it was signed by Sigmund Freud and Winston Churchill, both in their homes in London. In his later years, Land founded the Rowland Institute for Science where he found a vacant lot besides Charles River at Kendall Square.^[25]

Death

Land died on March 1, 1991, in Cambridge, Massachusetts, at the age of 81.^[27] Land's family, his wife, Helen, and two daughters, Jennifer and Valerie declined to disclose the cause of his death.^[27] Land himself disliked being written about, wanting to leave behind a legacy of published scientific work, rather than a cult of personality, and so, on his death, Land's family had a laboratory associate shred his personal papers and notes, a task that would take three years to complete.^{[7]: 150 [6]: 7}

He is buried in Mount Auburn Cemetery in Cambridge, Massachusetts.^[6]: 467
