William J. Mollema
1962

The work at this time was to enlarge the organ, and Mollema completed it along with George Price. Some pipes came from a practice organ in the chapel basement, while other ranks came from the Möller organ in Stetson Chapel on the campus of Kalamazoo College, which was being rebuilt at the time. A new Reisner console was installed in 1968, and further work was completed on the organ (releathering, new combination action, further tonal changes) by Lauck Pipe Organ Company in 1993.
