Silas B. Cobb

It is believed that up to the time this subscription was made, few, if any, ones had ever been made to education by a Chicago citizen at one time. A noble building, the Cobb Lecture Hall, now stands on the University campus, a monument of the builder's liberality and public spirit. - excerpted from History of Chicago by John Moses

Cobb was the earliest benefactor of the physical construction of the University of Chicago. While the original endowment for the university was funded by a donation from oil magnate and philanthropist John D. Rockefeller, it was stipulated that such money could not be used for buildings. The university thus looked for donors who could secure Rockefeller's endowment by providing funds for the campus' physical facilities. Cobb provided the funds for the campus' first building, Cobb Lecture Hall, which included classrooms, a recitation hall, and a chapel. Constructed in 1892 at a cost of $222,000, it is the oldest and most expensive of the campus' original sixteen buildings. Members of Cobb's family were also major benefactors to the university's construction, including sister-in-law Mrs. Jerome (Mary Warren) Beecher, who funded Beecher Hall, and son-in-law George C. Walker, who funded the Walker Museum.

Cobb has also been identified with semi-public enterprises. He made substantial investments in public utilities in Chicago and became a director of the Chicago Gas, Light and Coke Company. He was on the board of directors of two railroads, the Galena and Chicago Union Railroad and the Beloit and Madison Railroad, predecessors the Chicago and Northwestern Railway. Cobb was also appointed the president of the Chicago City Railway Company and was responsible for introducing cable cars to the city. He was additionally a director of the former National Bank of Illinois.
