In 1970, former U.S. Supreme Court Chief Justice visited the UCLA campus to take part in a ceremony marking the 25th anniversary of the Institute of Industrial Relations (IIR). As governor of California, Warren had signed a law creating the IIR at the Berkeley and UCLA campuses in 1945. Shown above are U.S Secretary of Labor James Hodgson, Prof. Lloyd Ulman of the UC-Berkeley IIR, Warren, and UCLA IIR director Prof. Benjamin Aaron. The IIR is now called the Institute for Research on Labor and Employment. Other photos from the event are shown below.
