Ethel Rosenberg, who was executed with her husband for espionage in 1953, was honored Monday by the City Council on what would have been her 100th birthday.

Three council members joined Manhattan Borough President Gale Brewer in issuing two proclamations lauding Rosenberg, a Lower East Side resident, for “demonstrating great bravery” in leading a 1935 strike against the National New York Packing and Supply Co., where she worked as a clerk.

The proclamations also said she was “wrongfully” executed for helping her husband, Julius, pass atomic secrets to the Soviet Union.

“A lot of hysteria was created around anti-communism and how we had to defend our country, and these two people were traitors and we rushed to judgment and they were executed,” said Councilman Daniel Dromm (D-Queens).
