Resigned to accept the position of Director of Research of the North American Philips Company Incorporated.

The following letter of resignation was received, addressed to the Board:

Gentlemen:
I hereby resign as Professor of Physics in the College of Literature, Science, and the Arts of the University and request that I be released from my position at the end of the present term so that I may accept the position of Director of Research of the North American Philips Company, Incorporated.
To leave the University after more than twenty years of service is not easy for me to do, and I assure you that I am taking this step with deep emotions of sorrow and only after a thorough canvass of the situation. My service here has been a very happy one, and I have been afforded every opportunity I deserve, and more. My associations on the campus have been a source of great joy, and I count myself very fortunate to have had the opportunity to spend such a large part of my life here.

Respectfully yours,

December 14, 1943 0. S. Duffendack
