Author and philosopher Lewis Mumford gave the commencement address yesterday morning at Radcliffe's graduation exercises in Sanders Theatre. President W.K. Jordan awarded a total of 430 degrees, including 229 B.A.'s, 124 graduate degrees, and 77 certificates of the Harvard-Radcliffe Program in Business Administration.

Mumford, the father of graduating senior Alison Mumford, used the philosophy of Ralph Waldo Emerson as his theme in addressing the graduating class. "First of all I would recall the familiar doctrine that underlies all Emerson's work, the doctrine of self-reliance," he said.

Jonathan Fay Prize

At the ceremonies summa cum laude graduate Marina von Neumann, from Setauket, L.I., was awarded the Captain Jonathan Fay Prize, given to that member of the graduating class "who during her course, by her scholarship, conduct, and character, has shown evidence of the greatest promise."

J. Seelye Bixler, president of Colby College and a Radcliffe trustee, gave the Invocation and the Benediction. Besides the other Radcliffe trustees and officers, Gordon M. Fair, Master of Dunster House, sat on the stage in Sanders to represent the Harvard Corporation.

Over one half of the Senior Class graduated with honors yesterday. Sixty-eight received cum laude degrees; 41, magna cum laude degrees; and seven, summa cum laudes.

Election of Elliot L. Richardson, Boston lawyer, to the Board of Trustees was also announced at the commencement exercises.
