Henry Williams Jeffers (January 4, 1871 – July 17, 1953) was an American dairyman and Republican Party politician who served as chairman of the New Jersey Republican State Committee.
He attended Wyoming Seminary in Kingston, Pennsylvania, before going on to Cornell University, where he received a B.S.
[1] Starting in his senior year at Cornell in 1898, Jeffers worked for the Walker-Gordon Dairy Farm, eventually becoming president in 1918.
At Walker-Gordon, based in Plainsboro Township, New Jersey, Jeffers invented a number of technological innovations streamlining dairy production, including the Jeffers bacteriology counter, the Jeffers feed calculator, and the Rotolactor (a rotary milking parlor, a sort of "carousel" for cows, invented in 1930).
During World War I he served on advisory boards for the United States Department of Agriculture and the American Food Administration under Herbert Hoover.
