Title: DuPont laboratory team discussing results of an experiment
Date(s): 1955
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: The industrial chemist today stands in sharp contrast with the lone wolf inventor common even a little more than a generation ago. Although the initiative and creative thought of the individual is still of prime importance, the modern researcher is a team player with a strong sense of cooperative effort. Pictured here is a DuPont lab team discussing results of an experiment.

Title: Dr. William H. Cloud studying a crystal
Date(s): 1955
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: Dr. William H. Cloud uses a torque magnetometer in studying the magnetic properties of single crystals. The crystal sample is inserted in a holder which is rotated between the pole caps of the electromagnet. Such studies help determine the ease or difficulty with which different types of materials can be magnetized. Dr. Cloud is one of the scientists in DuPont's Central Research Department whose fundamental research studies have led to an understanding of the mechanism of the unusual behavior...
