Edwin H. Land

OSA Honorary Member Edwin Land was born 7 May 1909 in Bridgeport, Connecticut, USA. He attended the Norwich Free Academy in Conn., and graduated in 1927. During his first year at Harvard University he studied chemistry but soon left for New York City.

Despite not having a lab or degree, Land was able to invent the first inexpensive filters capable of polarizing light. His breakthrough came when he realized that instead of attempting to grow a large single crystal of a polarizing substance, he could manufacture a film with millions of micrometer-sized polarizing crystals that were coaxed into perfect alignment with each other.

After developing the polarizing film, Land returned to Harvard, but still did not finish his degree. In 1932, he established the Land-Wheelwright Laboratories with his Harvard physics instructor to commercialize his polarizing technology. 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. The company was rename

Have you ever used a Polaroid camera? The portable device allows you to snap a photo, which is then printed straight out of the camera itself in seconds. This is all thanks to the work of Edwin Herbert Land. Land was born in Bridgeport, Connecticut on May 7, 1909 and attended the Norwich Free Academy, graduating in 1927. Following high school, he attended Harvard University where he conceived and produced the first modern filters to polarize light, patented in 1929. But it was through his Polaroid Corporation (founded in 1937) that Land was immortalized, for his invention and marketing of instant photography.

It was 1943 when his three-year-old daughter had asked him why she couldn't see a photo he had taken of her right away. Inspired, Land ended up creating a system of one-step photography: A camera that instantly printed photographs the moment they were captured.

In 1947, Land demonstrated the instant camera at the Optical Society of America’s winter meeting. Land used the principle of diffusion transfer to reproduce the image recorded

Edwin H. Land (1909 – 1991)

The origin of this idea is recorded by Land as follows:

I recall a sunny day in Santa Fe, N.M., when my little daughter asked why she could not see at once the picture I had just taken of her. As I walked around the charming town I undertook the task of solving the puzzle she had set me. Within an hour, the camera, the film and the physical chemistry became so clear to me.

The year was 1944, and Land was 35 years old. His daughter, Jennifer, was three years old. This agrees well with what he told me in Cambridge, UK, when he visited my laboratory in 1973.

Land wrote:

It was as if all that we had done in learning to make polarizers, the knowledge of plastics, and the properties of viscous liquids, the preparation of microscopic crystals smaller than the wavelength of light, the laminating of plastic sheets, living on the world of colloids in supersaturated solutions, had been a school both for the first day in which I suddenly knew how to make a one-step dry photographic process and for the following three years in which we made the very vivid
