Greta Berlin is a long-time activist for justice in Palestine. She married a Nakba survivor, Ribhi M. Kalla, in 1963 and they had two Palestinian/American children. Her second husband, Al Berlin, was an anti-Zionist Jew from Brooklyn who believed Israelis should learn to share the sandbox with Palestinians. She was the co-founder of the Free Gaza movement and was on one of the first two boats that successfully sailed into Gaza in August 2008. Her book, Freedom Sailors, is the story of how 44 raggedy activists made it to Gaza in spite of themselves. She was one of the spokespersons for Freedom Flotilla I when all six boats were attacked by the Israeli navy in international waters and ten passengers on board the Mavi Marmara were murdered by Israeli commandoes. She has written another book called "The Big But" under her maiden name, a self-help guide for people who have never traveled outside the US.
