Professor Sears Crowell's interest in marine biology began when he took classes at the Children’s School of Sciences in Woods Hole, Massachusetts. As a teenager, he worked at the Marine Biological Laboratory at Woods Hole, where he completed most of his research throughout his career. He focused his investigations on hydroids, sea anemones, and jellyfish.
Highly involved in the science community, Dr. Crowell served as trustee for the Marine Biological Laboratory and was named trustee emeritus in 1979. He also served two terms on their executive committee and was secretary of the board of trustees for two years. He was the first program officer for the American Society of Zoologists and the first managing editor of their publication, American Zoologist. Dr. Crowell also served as chairman of the zoology section of the Indiana Academy of Science from 1949 to 1950. He was a member of the Indiana University faculty for 31 years.
Limited to a Bolex, a tripod, a light meter, and 100 feet of Kodak 16mm B&W reversal film, we captured the film digitization phase of the Media Digitization and Preservation Initiative (MDPI) at Indiana University in Bloomington, IN. The film was shot in chronological order of the MDPI film digitization process and all editing was done in camera.
Fifteen million families’ move each year – and three-fourths of them merely change addresses within the same county. They move because they want a better place to live; they need not only houses or shops or schools but also police, fire protection, sanitation, and many other services that can only be provided by a community. And there are more and more people moving – more and more homes built on what is, after all, only a limited amount of land. This land must be used wisely: a planning engineer, similar to ones called in by communities across the country, describes the problems that a community must deal with when its population increases five-fold in a few years, and mentions some of the steps that are taken to provide for future planning and development. Most important are the procedures taken to stop and reverse the tendency for some areas to turn into slums; the program concludes with a short outline of Federal plans for urban redevelopment, and a plea to the viewer to take more active interest in his city.
Shows how money is used in place of the exchange of goods and services. Illustrates early use of snake skins, claws, and fishhooks for barter. Demonstrates by contrast how a pig can be traded for a horse on the farm, but cannot be traded for a dress in town. Traces a marked dollar bill given by a newsboy to a storekeeper as it passes through many hands until it is finally returned to the newsboy by a housewife.
