UBImusD13. Folder: Michigan Union (built 1919), exterior views. no. 246
Allen B. and Irving K. Pond, of Chicago, architects. Construction for the Michigan Union began in 1916. Previously, the renovated residence of Judge Thomas M. Cooley was used as the Union clubhouse. Before the four-story building officially opened for student use in 1919, it was used in a partially finished state as a barracks for the Students' Army Training Corps. By 1925, the pool in the basement and the library on the second floor of the building were completed. Several additions were made to the Union in the 1930's and 1950's.
IMB (Irvine, Michigan, Brookline), a collaboration between the University of Michigan, the University of California at Irvine, and the U.S. Department of Energy, was an experiment designed to determine the ultimate stability of matter. One of nine interesting events from the IMB detector in its first 204 live days of running. Similar to proton decay but rejected.
