Invitations received by Eccles from business, government, and civic leaders, friends, family members, and acquaintances requesting his participation and attendance at various events. Social invitations sent to the Eccles home, however, are not included. Because of his busy schedule, Eccles declined many more invitations than he accepted. He was invited to every presidential inauguration between 1951 and 1977, but apparently attended none of them. This correspondence is arranged chronologically.
