A large portion of this collection is photographs of Julius Sumner Miller as an educator and physicist performing experiments in different parts of the world. He taught in Australia, South Africa, Canada, Europe, and in the United States, where he became well known as "Professor Wonderful" for his work on Walt Disney's "Mickey Mouse Club." As a student, and later a friend, of Albert Einstein, Miller amassed a large amount of Einstein memorabilia which is also contained within the collection. Additionally there are manuscripts by Dr. Miller, a large collection of stamps from almost every country in the world, and notes on various demonstrations given by Miller during his fifty years of teaching.
