Geometric Model by Robert Chaffe, a Student of A. Harry Wheeler, Hyperbolic Paraboloid

National Museum of American History

Object Details

teacher of maker
Wheeler, Albert Harry
Chaffe, Robert
Description
Suppose two opposite sides of a rectangle are joined by straight lines parallel to the other two sides. Lifting two opposite corners of the rectangle—and keeping the lines taut—one obtains a saddle-shaped figure known as a hyperbolic paraboloid.
This model of a hyperbolic paraboloid was made from balsa wood by Robert Chaffe, a high school student of A. Harry Wheeler in the class of 1937. It is likely that this person is Robert C. Chaffe (1918–1991) who was born in Connecticut, attended high school in Worcester, Massachusetts, graduated from the Worcester Polytechnic Institute in 1942, and seems to have spent his career as a salesman and sales engineer in Worcester and nearby Auburn.
