Born into a family of farmers and sugar mill owners, Guimarães was descended from Brazilian nobility.

Guimarães joined the PCB in 1931 and played a role in planning the Brazilian communist uprising of 1935, which ultimately failed. Arrested in 1938–1939, he was released in 1945 following amnesty for political prisoners. Guimarães did not rejoin the PCB and died in a car accident at the age of 65.

He belonged to a family of farmers and sugar mill owners in Rio de Janeiro, specifically in the cities of Niterói and Barra Mansa.
In 1910, his father was removed from the public office he held for supporting Rui Barbosa's candidacy for the presidency of Brazil. With money from his mother, his family moved to Europe, initially in Paris and, starting in 1914, in England, where he enrolled in Eton College. Guimarães completed the course five years later. He returned to Brazil and enrolled in the Polytechnic School of Rio de Janeiro, but abandoned the course in late 1921.

Guimarães ventured into an orange export business but did not achieve success.
Honório de Freitas Guimarães was married to Maria de Figueiredo, the youngest daughter of the . Maria had been part of the intellectual circles in Paris at the time, and as a result, around 1925, Guimarães became interested in socialism and communism.

The armed movement failed, and the leadership of the PCB ordered the execution of Antônio Maciel Bonfim's consort, Elza Fernandes, on suspicion of betrayal. Guimarães became involved in her execution.
The Brazilian communist uprising of 1935 was followed by a strong repression against all government opponents. Guimarães took over the position of secretary-general of the PCB for a few months after the arrest of several members, replacing Miranda.
