She married Rabbi Philip Spectre, and the couple moved in 1967 to Ashkelon, Israel, where she served on the faculty of Jewish Studies at Achva College of Education.

Barbara Spectre has garnered attention for her quote, from an interview in an IBA News report about the wave of anti-semitism in Sweden due to Muslim immigration.
