By 1927, more space was needed and VanderCook purchased a large brownstone residence at 1655 Washington Blvd. (and Paulina), later adding adjacent buildings at 1653 and 1657 Washington Blvd. Students took required academic and education courses at nearby Lewis Institute. The root of the relationship between VanderCook College of Music and the Lewis Institute (later Illinois Institute of Technology) was the close friendship between Hale A. VanderCook and George L. Tenney, better known as “Doc” Tenney. “Doc” taught vocal music at the Lewis Institute and directed choirs in some of the largest churches in the Chicago area.
