The engineering firm that became Lockwood Greene was founded by David Whitman, a mill engineer, in 1832. Amos D. Lockwood, a consultant, succeeded Whitman and entered a partnership with Stephen Greene in 1882. The firm specialized in industrial engineering and construction; they designed and built a wide variety of structures and work environments worldwide over the next century. Lockwood Greene was acquired by CH2M HILL in December, 2003. Before its acquisition by CH2MHILL it was reportedly the oldest industrial engineering, construction, and professional services firm in the United States.
Arthur Ehrat Papers
Fleckner, John A., 1941-
Arthur Ehrat invented and patented a breakaway basketball rim, fashioning his prototypes from bolts, metal braces and one key part: a piece of the heavy-duty coil spring on a John Deere cultivator. His invention helped to revolutionize the way basketball is played because players could slam dunk the ball with fewer injuries and without bending the rims or breaking backboards. This collection includes correspondence, legal documents --such as patent papers, litigation files and licensing agreements --photographs and sketches that relate to the basketball invention, as well as materials regarding his two field spreader patents and other invention ideas.
