McLean Hall - the first 100 years: 1910-2010

MacLean Hall was the third of four buildings erected to anchor the four corners of today's Pentacrest. Its cornerstone was laid in 1910 and over the years MacLean Hall has been the home of Physics, Astronomy, Mathematics, Statistics & Actuarial Sciences, an astronomical observatory, and even some the university's art studios. The predecessor of today's radio station WSUI was first set up in MacLean Hall. Today, MacLean Hall is the home of the Departments of Mathematics and Computer Science.

Clapp-Eastham 1 kw transmitter. While no photo has been found for the original 2 kw Clapp-Eastham transmitter used by U of I's radio station 9YA, the 1914 radio pictured here is from the same era and it gives you a sense of the radio technology used a century ago. The Clapp-Eastham Co. closed in 1929.
