Isaac Wheeler Geer

Isaac Wheeler Geer (February 1, 1873 – June 20, 1953) was an executive with the Pennsylvania Railroad known for his involvement in labor disputes.

Education and early career
Geer was born in Plainfield, Connecticut, to David and Eunice Witter Geer. After graduating from Phillips Academy, Andover, Isaac attended Yale, earning several awards in science and mathematics.

Labor dispute (1921)
In 1921 Geer became embroiled in a dispute with labor unions. The unions claimed that Geer had authorized railroad executives to "defame" labor unions in order to force them to reveal information on the unions and on wage cuts. The unions produced a letter purportedly by Geer; but Geer denied having written it. During hearings of the United States Railway Labor Board, union lawyers failed to prove the authenticity of the letter.

On October 23, 1901, Geer married Margaret Worth Thornton, sister of Sir Henry Worth Thornton, cousin of Judge William Wheeler Thornton, and niece of Dr. William Patton Thornton.

The Geers had two children: Helen Thornton Geer, professor of library science and Margaret Worth Geer.
