Cornell professor emeritus Gerald Rehkugler tells the story of Cornell's Rau Model Plow Collection and illustrates the evolution of the plow over time in his April 21, 2011 presentation to the Cornell Association of Professors Emeriti (CAPE).
The Rau Collection was acquired in 1868 by the first Cornell president Andrew Dickson White. The models trace the development of the plow from around 3000 B.C.E. to the mid 1860's.
