He is best known for co-founding the Boston Guardian, an African-American newspaper in which he and William Monroe Trotter published editorials excoriating Booker T. Washington for his accommodationist approach to race relations.
Forbes was born to enslaved parents in Mississippi, worked as a laborer at Harvard University, and graduated from Amherst College in Massachusetts before gaining a national reputation as a journalist.
The group, which included his classmate Lewis as well as William Monroe Trotter, Archibald Grimké, Butler R. Wilson, Clement G. Morgan, and other black intellectuals, was critical of Booker T. Washington's accommodationist approach to race relations.
Forbes stayed put, becoming a neighborhood institution at the West End branch, where he worked for 32 years without taking a single sick day.
It opposed Mr. Washington's doctrine of surrender and compromise and it opposed this doctrine with editorials that flamed and scorched and George Washington Forbes wrote them....Whatever has been accomplished from that day to this in beating back the forces of surrender and submission and in making the American Negro stand on both feet and demand full citizenship rights in America, has been due in no small degree to Forbes' work on the Boston Guardian.
[2] He played a small role in the founding of the Niagara Movement, the precursor to the National Association for the Advancement of Colored People (NAACP), but from about 1910 he retired from politics and focused on his work at the library.
[1] He continued to write, contributing articles on black history and race relations to the Springfield Republican and the Boston Transcript, and reviewing books for The Crisis (the official magazine of the NAACP).
A warm tribute to Forbes, originally printed in Yiddish, appeared in The Jewish Daily Forward and was reprinted in English in the Crisis and Opportunity: A Journal of Negro Life.
The article hailed Forbes as a "friend of the race," praising not only his intellect but his unfailing kindness: Many times a college or high school student wrestled with a certain subject.
