Tree of Life Congregation was formed in Pittsburgh, Pennsylvania, in 1864 as a breakaway group from Rodef Shalom, an Orthodox synagogue founded in 1854 which began adopting Reform practices following the visit of Rabbi Isaac Mayer Wise to the city. The initial group of 16 members met in the home of Gustavus Grafner. Then called by its Hebrew name, Etz Chayyim, the congregation was chartered in 1865 and acquired land in Sharpsburg for use as a cemetery. The congregation met in temporary locations in the downtown area over the coming years, until in 1883 it bought a former Lutheran church property downtown. At that point, it became known by its English name, Tree of Life. In its early years, Tree of Life was the city's center for Orthodox Judaism, and attracted Orthodox Jewish immigrants from Eastern Europe. In 1883, it shortened the traditional Orthodox prayer service, and in 1886 became affiliated with the Jewish Theological Seminary Association, a rabbinical training institute which was at the time an Orthodox institution but which developed the Conservative ideology in the early 1900s. Around 1916, Tree of Life joined the national Conservative Jewish network, the United Synagogue of America. In 1906, the congregation began constructing a permanent home on Craft Avenue in the Oakland neighborhood of Pittsburgh. The synagogue opened in 1907 with sanctuary seating for 750. English-language prayers were introduced the same year. Beginning in the 1920s, Tree of Life shifted further toward left-wing Conservative Judaism under the direction of Rabbi Herman Hailperin, who led the congregation for 45 years. Among the practices Hailperin instituted were organ music during the prayer services, the elimination of the rabbinically-mandated second day of festival observance, the election of women to the temple's board of trustees, the calling of women to the Torah reading, and counting women as part of the minyan. In 1953, Tree of Life moved into its present building in the Squirrel Hill neighborhood of Pittsburgh. The land for the new structure was gifted by then-synagogue president Charles J. Rosenbloom. The synagogue symbolically showed its ties to Israel with a cornerstone hewn from limestone quarried in Jerusalem. The structure initially opened with a library, kitchen, an arts and crafts store, a stage, and vestry rooms. In 1959 the congregation broke ground on a 1,400-seat sanctuary fronted by "rows of swirling, modernistic stained-glass windows illustrating the story of creation, the acceptance of God's law, the 'life cycle' and 'how human-beings should care for the earth and one another". In 1995, membership numbered 850 families.
Tenants and merger
In the 2000s, an aging membership and the migration of the Jewish community to suburban neighborhoods led to decreasing synagogue membership. Tree of Life began renting space in its building to other congregations. In 2008, Congregation Or L'Simcha, founded by Rabbi Chuck Diamond in 2005, began holding services in the Tree of Life building. In 2010, the two congregations voted to merge and became known as Tree of Life – Or L'Simcha Congregation. The merger added 120 congregants to Tree of Life's membership rolls, bringing the combined membership to 530 families. In April 2010, Dor Hadash, a Reconstructionist congregation, began renting space in the Tree of Life building. New Light, a Conservative congregation, left its home of 60 years in 2017 and carried its Torah scrolls in a procession to Tree of Life, where it also began renting space.
Mass shooting
A mass shooting occurred in the Tree of Life synagogue during Shabbat morning services on October 27, 2018. A gunman entered the building shouting antisemitic statements and opened fire, killing eleven and injuring seven, including four police officers. The sole suspect, Robert Bowers, was apprehended at the scene.
Leadership
The congregation elected its first spiritual leader, Rabbi Michael Fried, a graduate of the Jewish Theological Seminary, in 1898. The longest-tenured rabbi of the congregation was Rabbi Herman Hailperin, who acceded to the position in 1922 while in his early twenties, the same year he was ordained by the Jewish Theological Seminary; he actively served for the next 45 years, being named rabbi emeritus in 1968. Following is the rabbinical leadership of the Tree of Life Congregation:
Rabbi Michael Fried
Rabbi Rudolph Coffee
Rabbi Morris Mazure
Rabbi Emeritus Herman Hailperin
Rabbi Solomon Kaplan
Rabbi Emeritus Alvin K. Berkun
Rabbi Stephen Listfield
Rabbi Chuck Diamond
Rabbi Hazzan Jeffrey Myers
The synagogue's lay leadership established a tradition of volunteering and support for Jewish social service activities. Alexander Fink, the synagogue president from 1873 to 1892, was also a founder of the city's Hebrew Benevolent Society and later served as president of the United Hebrew Relief Association. When the synagogue established its new home in Squirrel Hill, facilities were given over for meetings of junior and senior Hadassah, the Women's League for Traditional Judaism, Young Judaea clubs, and Boy Scouts and Girl Scouts troops.
