Moshe (Moritz) Wallach (28 December 1866^[1] – 8 April 1957^[2]) was a German Jewish physician and pioneering medical practitioner in Jerusalem. He was the founder of Shaarei Zedek Hospital on Jaffa Road, which he directed for 45 years.^[3] He introduced modern medicine to the impoverished and disease-plagued citizenry, accepting patients of all religions and offering free medical care to indigents.^[4] He was so closely identified with the hospital that it became known as "Wallach's Hospital".^[1][5][6] A strictly Torah-observant Jew, he was also an activist in the Agudath Israel Orthodox Jewish movement.^[7] He was buried in the small cemetery adjacent to the hospital.

Moshe Wallach was one of seven children^[4] born to Joseph Wallach (1841–1921), a textile merchant originally from Euskirchen, and Marianne Levy of Münstereifel. His parents moved to Cologne following their marriage in 1863. Joseph Wallach was a founder of Adass Jeshurun, the Cologne Orthodox community, which he later served as president.^[5]

In his youth, Wallach attended the Friedrich-Wilhelm-Gymnasium, Cologne [de] and a Jewish school run by the Cologne Orthodox community.^[1] He studied medicine at the University of Berlin and University of Würzburg, and received his Doctor of Medicine degree in 1889.^[1][5] In 1890 he was chosen by the Frankfurt-based Jewish Conference for the Support of the Jews in Palestine to emigrate to Palestine and carry out its plans to open a modern Jewish hospital in Jerusalem.^[8] Wallach first opened a clinic and pharmacy in the Armenian Quarter of the Old City.^[9][10][11] He also worked in the Bikur Holim Hospital as a women's and children's physician, ophthalmologist, and surgeon specializing in neck surgery.^[5] He was the first to perform tracheotomies in Jerusalem,^[12][13] and performed many ritual circumcisions.^[10][14]

In 1896^[1] Wallach returned to Europe to raise funds for the new hospital, collecting donations in Germany and Holland.^[14] Upon his return to Jerusalem, he purchased a 10-dunam (2.5 acre) plot of land located 3 kilometres (1.9 mi) outside the Old City Walls on what would become Jaffa Road.^[4] He registered the land in his own name with the help of the German consul in Jerusalem, Dr. Paul von Tischendorf, who also helped him procure building materials from Germany.^[11][15]

Shaare Zedek Hospital opened on January 27, 1902^[16] with 20 beds, an outpatient clinic, and a pharmacy.^[17] With most of the hospital's patients living in the Old City, a 20-minute donkey ride away,^[5][16] and a dearth of in-house staff, Wallach often made house calls to determine whether a case actually warranted hospitalization. If transporting to the hospital would be dangerous, he performed curettage; otherwise, he accompanied the patient on a stretcher back to the hospital surgery.^[14]

In addition to departments for internal medicine, maternity and children,^[4] Wallach later opened an infectious diseases department which was the only one in Jerusalem to treat polio.^[18] During the milk shortages of World War I, Wallach bought several milk cows and built a cowshed and grazing field for them behind the hospital.^[5][16] The herd was gradually increased to 40 cows^[19] and became a source of revenue, especially for kosher-certified milk sales for Passover.^[12]

Wallach, who for several decades was the only in-house physician at Shaare Zedek,^[14] ran the hospital as a strictly Orthodox institution. He insisted on strict Sabbath observance and a high level of kashrut in the hospital,^[17] and personally supervised the milking of the cows.^[4] He arranged for an electric generator to service the hospital so that it would not have to rely on electricity provided by the power station, where Jews worked on Shabbat.^[20] He set aside part of the field adjacent to the hospital to the growing of wheat for shemura matzo and supervised the baking of matzos for Passover. For Sukkot, he erected a 10 metres (33 ft) by 4 metres (13 ft) sukkah in the hospital courtyard to accommodate both eating and sleeping.^[21]

The language of the hospital was German or Yiddish; Wallach refused to speak in Hebrew, the language of Torah study, in a secular institution.^[14] Before the rise of Nazism, Wallach ordered all hospital correspondence to be conducted in German; afterwards he allowed letters to be written in Rashi script, a Hebrew typeface.^[5][22]

Wallach became a well-known and respected personality in Jerusalem. He was invited to every political and diplomatic reception that took place during the Ottoman and British Mandate periods. The British Governor of Jerusalem Ronald Storrs was a personal friend of Wallach's; he expedited the doctor's request for the annual delivery of matzos to the hospital for the Passover holiday. Wallach was also close to leaders of the Old Yishuv, including Rabbi Yosef Chaim Sonnenfeld. He was a personal friend of Rabbi Jacob Israël de Haan, a political spokesman for the Haredi community in Jerusalem who was assassinated in 1924 just outside Shaare Zedek Hospital as he was returning to the hospital synagogue for evening prayers.^[15]

Wallach was the personal physician of many Torah leaders of the Old Yishuv, among them Rabbi Chaim Hezekiah Medini, whom he treated in Hebron,^[24] Rabbi Yosef Chaim Sonnenfeld, Rav of Jerusalem,^[8] Rabbi Yosef Tzvi Dushinsky, the first Dushinsky Rebbe,^[25] and Rabbi Solomon Eliezer Alfandari, who lived in the Ruchama neighborhood (today Mekor Baruch).^[26] He also treated King Abdullah I of Jordan.^[8]

Wallach also treated the previous Lubavitcher Rebbe, Rabbi Yosef Yitzchak Schneersohn.^[27] The Rebbe had suffered a kidney attack, and Wallach was aboard and treated him and cared for him until he regained his strength. Soon after, Wallach approached Rabbi Schneersohn to request a manner of penance ("kapparah"). When asked for what, he replied that his presence caused the Rabbi's illness, given that God would not have allowed such an important leader needed by all Jews to become seriously ill without a doctor nearby. The Rebbe recounted this incident to his son-in-law, Rabbi Menachem Mendel Schneerson, who in turn recounted it in a public talk in 1987, as an example of true humility and contriteness.^[28]

Wallach was a dedicated physician and a demanding and exacting employer.^[14][29] He was known to shout at nurses and patients alike who did not follow his instructions to the letter.^[4] His first pharmacist quit because he was unable to tolerate Wallach's behavior.^[30] However, Wallach also had a sense of humor. Once he was leaving the hospital late at night when he encountered a woman waiting by the locked gate. She did not know who he was, but begged him to let her in for a few minutes to see her husband, who had had an operation the previous day. "Quick, before that crazy man Wallach comes", she said. Dr. Wallach let her in, and received her profuse thanks when she came out again. "What is your name?" she asked. "You are such a kind person". "I am the crazy man Wallach", he replied.^[31][14][32]

Despite his outer gruffness, Wallach had a kind heart. He adopted a young Syrian girl named Bolissa who had been brought to the hospital by her father and was subsequently abandoned there.^[14][15] He personally assisted poverty-stricken immigrants to find housing and jobs,^[3] and did not charge indigent patients.^[4] Before World War I, he intervened with Jamal Pasha, Ottoman leader in Palestine, on behalf of Jews who had been conscripted into the Turkish army or who were in danger of being expelled from the country.^[33] He also helped members of his extended family in Germany immigrate to Palestine after the rise of Nazism in the 1930s.^[34]

Wallach was scrupulous in his own mitzvah observance.^[11] He engaged a teacher to study Talmud with him and spent much time learning with Rabbi Yosef Chaim Sonnenfeld, leader of the Old Yishuv.^[35] Whenever he traveled on house calls, he brought along a Book of Psalms to recite on the road.^[21]

Wallach never married. A wealthy German donor to the hospital, Yehoshua Hearn, wanted him to return to Germany to marry his daughter, but after consultation with Rabbi Sonnenfeld, Wallach determined that he would not leave the land for any reason. Later, when the girl agreed to travel to Palestine, Wallach arranged a shidduch between her and his brother Ludwig, who worked as a clerk at Shaare Zedek Hospital.^[15][36] Wallach resided in rooms in the hospital until his final day.^[12][8][15]

Wallach retired at the age of 80. He was succeeded as director of Shaare Zedek by Dr. Falk Schlesinger, another German-Jewish physician.^[14]

Wallach was feted on several occasions, beginning with a seventy-fifth birthday celebration at a hotel, which was attended by British Mandate health officials.^[14] Before his eightieth birthday, a Torah scroll was commissioned in his honor. Upon its completion three years later, Wallach donated it to the hospital synagogue.^[37] Two banquets were held in honor of his eighty-fifth birthday – one in the hospital, attended by the Sephardic Chief Rabbi of Israel, Ben-Zion Meir Hai Uziel, the Minister of Health, representatives of the Doctors Union, and representatives of the Old and New Yishuvs; and the second in the office of the Jerusalem mayor, Shlomo Zalman Shragai, who bestowed a commendation on Dr. Wallach for his years of public service.^[38] In honor of his ninetieth birthday, Wallach was awarded an honorary degree from the medical faculty of the Hebrew University of Jerusalem. The city of Jerusalem also named him a Yakir Yerushalayim (Worthy of Jerusalem); however, Wallach died the day before the presentation ceremony took place.^[5]

Wallach died on April 8, 1957, at the age of 90. He was buried in the small cemetery adjacent to the hospital, on land he had given to the burial society of the Perushim and Ashkenazim of Jerusalem to use as a temporary burial ground during the 1948 Arab-Israeli War.^[39] After the war, most of the 200 graves in this cemetery were relocated to permanent cemeteries, but a handful of graves remained, including that of Rabbi Yosef Tzvi Dushinsky, the first Dushinsky Rebbe, who died in Shaare Zedek Hospital in 1948.^[25] Per his request, Wallach was buried beside the Dushinsky Rebbe, whom he considered his mentor.^[2][6][14]

According to Schwester Selma, over half of Jerusalem attended Wallach's funeral.^[14] He was eulogized by Who's Who in Israel as the Israeli medical profession's "spiritual leader for two generations".^[40] The Jerusalem municipality named the small street west of Shaare Zedek Hospital "Moshe Wallach Street" in his honor.

Prime Minister of Israel Yitzhak Rabin paid tribute to Wallach in a 1995 address in the United States Capitol rotunda inaugurating the Jerusalem 3000 celebrations. In a speech titled "My Jerusalem", Rabin began:

"Jerusalem has a thousand faces – and each one of us has his own Jerusalem. My Jerusalem is Dr. Moshe Wallach of Germany, the doctor of the sick of Israel and Jerusalem, who built Sha'arei Zedek hospital and had his home in its courtyard so as to be close to his patients day and night. I was born in his hospital. I am a Jerusalemite".^[41]
