Biography: Donald J. Angus (1887-1966)

Angus was a self-made engineer-inventor. Although he never completed high school, he did attend, as an occasional student, engineering classes of his choice at the University of Wisconsin and Michigan State University. One of his early major projects was design and installation of hydraulic plant and distributing system for the district at Williams, Lawrence County, Ind. (1909-1912). The entire Bedford Stone District of Indiana, one of the largest industrial eletrifications in the United States, was managed by Angus for some time after the completion of the project. He became progressively expert on electrical measuring and recording devices, and was selected during World War I to design a totalizing meter for the Mississippi River Company plant at Keokuk, Iowa. During his lifetime he was granted 47 patents on electrical and mechanical devices. He joined John W. Esterline in 1910 to create The Esterline-Angus Company.
