Helen Levi Travis, 86, a social activist whose conviction for violating a U.S. ban on travel to Cuba was thrown out in a 1967 Supreme Court ruling, died Nov. 14 in San Pedro. The cause was not disclosed.
Travis became involved in socialism as a Barnard College student in the 1930s, when she joined students in a trip to Soviet Union.
With her first husband, Abbott Simon, who was a leader of the radical American Youth Congress, she helped establish a clandestine safe house outside Prague to shelter anti-Fascist activists. She later returned to the U.S., became an auto worker, and was divorced from Simon.
Her second husband, Robert C. Travis, was a principal organizer of the violent 44-day strike in Flint, Mich., in 1936-37 that forced General Motors to recognize the United Auto Workers.
