Four TLSs, signed "D. E.," "as ever, D. E.," "D. D. E.," and "Uncle Ike," each one page, three typed on 7 x 10.25 personal letterhead and one on 6.75 x 8.75 White House letterhead, dated between 1961 and 1966. The letters are addressed to his aide, Brigadier General Robert L. Schulz, or to Schulz's wife, Dorothy. The earliest letter, signed as president, January 11, 1961, in part: "I am sorry to learn from Ann that your own contribution to the NBC program of last evening was 'washed out'—presumably because the Vice President was an added starter and, I guess, ranked you." The second, dated September 17, 1962, in full: "Even gloomy, rainy days have their compensation—in his instance it is your anniversary that clears the skies. Happy Birthday!" The third, September 15, 1965, in part: "Because for so many years we have worked together it is sometimes difficult to say 'Happy Birthday' without resorting to clichés that have been overworked, by me." The last letter, written from Walter Reed Hospital on May 13, 1966, in full: "Thank you and the children for your nice card. I appreciate your thoughtfulness and assure you that you made my day a bit brighter." In overall fine condition. Accompanied by two original mailing envelopes. From the collection of Brigadier General Robert L. Schulz, longtime military aide to Dwight D. Eisenhower.
