From 1900 to 1920 many new buildings were built on campus, including buildings for the dental and pharmacy programs, a chemistry building, a building for the natural sciences, Hill Auditorium, large hospital and library buildings, and two residence halls. The university built up its reputation for research in 1920 by rebuilding the College of Engineering and making a group of 100 industrialists, or businessmen, to help guide research. UM's reputation as a very good national university also began to grow at this time. The university became a favorite other choice for Jewish students from New York in the 1920s and 1930s when the Ivy League schools made a limit to the number of Jews to be admitted. Because of this, UM gained the nickname "Harvard of the West," which became commonly joked about in reverse after John F. Kennedy called himself "a graduate of the Michigan of the East, Harvard University" in a speech.
