Welch Hall, named after the first president of the school, Adonijah S. Welch, was constructed in 1896 to serve as the new training school building on the Michigan State Normal School (MSNS) campus. The building held classroom space for grades K-8, offices, and an assembly room that could accommodate 400 children. After the MSNS reached collegiate status in 1899, attendance greatly increased, resulting in east and west wings being added to Welch in 1900, and a north-west wing being added in 1909, to create more classroom space for the growing student population. The training school moved to the Roosevelt building when it was constructed in the 1920s, and for the next forty years Welch Hall served as the home for many different academic departments. In the 1960s, Welch was converted into office space and it began being used as the main administrative building on-campus, which is still the purpose it serves today.
Welch was nearly demolished in the 1980s, as decades of poor maintenance caused the building to significantly deteriorate. Dr. Andrew Nazzarro, the man who established the Historic Preservation program at EMU 1979, started the “Don’t Squelch Welch” button campaign to promote support to save the building. This campaign was a success, because in 1985 a $2.5 million federal grant was awarded to EMU to renovate Welch Hall and ensure that the building could continue to serve the EMU community.
