In 1921, Hadassah nurse Bertha Landsman created Palestine's first permanent infant welfare station, Tipat Halav (Drop of Milk), in Jerusalem. The overwhelming success inspired Hadassah to expand the program, delivering fresh milk to needy families by "donkey express." Hadassah also opened a hospital in Tel Aviv, the city's first hospital. Under Hadassah's philosophy of "devolution," it initiated and developed a number of facilities and projects and then transferred them to the appropriate municipalities. Hadassah transferred administration of this hospital to the Tel Aviv municipality in 1931.
