Ralph Oscar Yeager

[2] Yeager was born August 16, 1892, in Danville, Illinois, where he graduated from high school.

Yeager supervised construction on the U.S. Post Office Building (1915–1917) for Yeager & Sons, Contractors, served as a second lieutenant in the army during World War I (1917–1918), and was variously employed architectural offices in Chicago, Terre Haute, and Madison, Wisconsin.

In 1922, he established his own practice in Chicago before returning to Terre Haute the next year (1923) to become a partner in the firm Miller & Yeager.

Miller & Yeager, located at 402 Opera House Building, Terre Haute, Indiana, was responsible for many landmarks in Indianapolis and greater Indiana, and a number have been listed on the National Register of Historic Places.

In 1946, he was the sole surviving partner of Miller & Yeager and merged the firm with Vonnegut, Bohn & Mueller and Pierre & Wright, both of Indianapolis, Indiana.
