Dear Bob: I accept with deep regret, but with complete understanding, your decision to retire from the Foreign Service on October 31, 1959, and at the same time I accept your resignation as Under Secretary of State for Political Affairs, and Chairman, Operations Coordinating Board, as of December 3, 1959.1
For more than forty years you have served with great effectiveness and distinction in various capacities in that most difficult and most important area--our relationships with other countries. You have skillfully carried out the most difficult negotiations and well earned your unofficial title of our number one "trouble shooter." Though you have consistently played down your own accomplishments, I am aware, as I am sure many Americans are, of the vast contribution you have made, on behalf of all of us, in your efforts to advance a just and secure peace.2
It has been my privilege to work with you on many an assignment since early 1941, when we were together in Algeria.3 I have always respected your judgment, admired your effectiveness, and valued highly your friendship. I hope that, if need be, Secretary Herter and I may call upon you from time to time for the special advice that you, because of your experience, training and sensitive perception, can so ably give.4
Along with your associates in the government, Mrs. Eisenhower and I wish for you and Mildred much happiness in the many years that lie ahead.5
With warm personal regard, As ever
