After getting an education at the Augusta High School and Phillips Exeter Academy, Fuller came to Boston in 1861, and for several years devoted himself to business, beginning as a clerk in the office of Page, Richardson & Company.

[1] Although Fuller never took a university course, he was such a constant student throughout his life that he attained a culture so broad and thorough that many readers were surprised to learn that he did not hold a college degree.

[1] His editorial work not only made him known to the legal profession, but its incidental correspondence brought him into direct touch with many leading lawyers throughout the United States.

He felt, however, a keen interest in public affairs, and was always ready to give encouragement and effective personal work to what may be called conscience issues like civil service reform.

For many years he devoted much time and energy to the duties of manager of the Brookline Comedy Club, a position requiring peculiar tact and patience.
