A Palestinian doctor who was born and raised in the Jabalia refugee camp in the Gaza Strip, Izzeldin Abuelaish is an infertility specialist who lives in Gaza but works in Israel. The Gaza doctor has been crossing the lines in the sand that divide Israelis and Palestinians for most of his life--as a physician who treats patients on both sides of the line, as a humanitarian who sees the need for improved health and education for women as the way forward in the Middle East. And, most recently, as the father whose daughters were killed by Israeli soldiers on January 16, 2009, during Israel's incursion into the Gaza Strip.
