The day will be dedicated to the memory of a deceased resident of the block, the Hon. Bertram L. Baker, who in 1948 became the first black person ever elected to political office in Brooklyn.
He served for 22 years in the State Assembly and in the 1960s was Majority Whip of the Assembly.
(Disclosure: He also happens to have been our grandfather.)
