in Ein Karem in southwest Jerusalem under the direction of then-director general Kalman Mann. The Hadassah Women's Zionist Organization of America again assisted with funding, and the somewhat out-of-the-way location was chosen in part because an appropriate site was difficult to obtain in the city-center, and Hadassah owned a large plot in Ein Karem. The hospital was designed by Joseph Neufeld, a pioneer of International Style architecture in Israel. Prior to the opening of a 19-story hospital tower in 2012, Hadassah Ein Karem had 700 inpatient beds. The hospital complex consists of 22 buildings, including the Hebrew University of Jerusalem schools of medicine, dentistry, nursing, public health and pharmacology. Hadassah's director is Professor . Notable physicians include Avraham Rivkind, founder and director of the hospital's trauma center, Ahmed Eid, head of the liver and kidney transplant unit, and Arie Eldad, head of the department of plastic surgery and burns unit. In March 2007, Jewish American billionaire William Davidson donated $75 million to the hospital. In 2012, the Sarah Wetsman Davidson Hospital Tower opened with 500 beds and 20 operating theaters. In 2008 Prime Minister John Key of New Zealand made a donation to the hospital. In April 2009, following an initiative of the Puah Institute, the hospital opened a fertility clinic for AIDS patients, the first such clinic in Israel. Prof. Shlomo Ma'ayan heads the clinic. Chagall windows The Ein Karem campus synagogue is illuminated by stained glass windows depicting the twelve tribes of Israel, created by Marc Chagall. Chagall envisaged the synagogue as "a crown offered to the Jewish Queen," and the windows as "jewels of translucent fire." The windows were installed February 1962. At the dedication ceremony, Chagall said: "A stained glass window is a transparent partition between my heart and the heart of the world...To read the Bible is to perceive a certain light, and the window has to make this obvious through its simplicity and grace... The thoughts have nested in me for many years, since the time when my feet walked on the Holy Land, when I prepared myself to create engravings of the Bible. They strengthened me and encouraged me to bring my modest gift to the Jewish people, that people that lived here thousands of years ago." New entrance pavilion In 2012, a new glassed-in entrance pavilion opened at the foot of the Davidson Tower which funnels all traffic entering the hospital. Alongside
