In August 1907, the synagogue's Board selected the architecture firm of
Pilcher and Tachau to design its fourth building to be built at Broad and York Streets. Samuel Elkin had left $60,000 to the congregation to be used for construction which was estimated to cost $150,000. The block until 1894 had been the site of
Forepaugh Park where
Adam Forepaugh presented circuses and spectacles, and where the
Philadelphia Athletics played in 1890 and 1891. It was developed in the late 1890s with residential homes, and Mikveh Israel and
Dropsie College built their complex in 1909 following the Jewish population up
North Broad Street. The one story Neo-Roman limestone building was dedicated on September 14, 1909. The congregation's Leon Elmaleh, Rabbi
Pereira Mendes of
Congregation Shearith Israel, and Philadelphia's Rabbi
Bernard Levinthal all spoke at the ceremony. During WWI, the Mikveh Israel Association applied for a Red Cross Auxiliary in the Southeastern Pennsylvania Chapter in May 1917. Leading women of the congregation established a work room in the adjoining Gratz College building where one day a week they made surgical garments and collected supplies. Dr.
Abraham A. Neuman (1890–1970) was rabbi from 1927 to 1943. Rabbi Neuman joined with
A. S. W. Rosenbach to preside over a special service in February 1932 to commemorate the bicentennial of George Washington's birth at which Dr. Rosenbach read Washington's letter to the congregation. During this period, the congregation counted prominent physician
Jacob da Silva Solis-Cohen and movie theater magnate and philanthropist
Jules Mastbaum as members. Mastbaum would gift the
Rodin Museum to the City of Philadelphia. The congregation celebrated its bicentennial the weekend of Thursday, November 28, 1940, concluding with a banquet at the Ritz-Carlton Hotel on Sunday, December 1, 1940. At this time, the congregation numbered 1,200 members. In December 1954, Mikveh Israel played a prominent role in Philadelphia's celebration of the tercentenary of Jewish settlement in North America. Reverend Elmaleh, then Minister Emeritus, blew shofar during the ceremony held in
Congress Hall. Dr. Neuman was succeeded as congregation rabbi by
David Jessurun Cardozo (1896–1972). Reverend Alan D. Corre (1931–2017) came to Philadelphia from Manchester, England at age 24 in 1955 and served as rabbi until 1963. The congregation voted unanimously in April 1959 to amend its constitution and allow women to serve as officers on its Board of Adjuntos including as congregation president. Dr. Lillian S. Alpers would be the first woman elected to the Board in November 1959.
Noam Chomsky (born 1928) grew up in Philadelphia at Mikveh Israel on North Broad Street where his father, Dr.
William Chomsky (1896–1977), ran the Hebrew school, was president of
Gratz College, and taught at
Dropsie College. Rabbi Ezekiel Musleah (1927–2020) joined Mikveh Israel as minister in 1964 and served in this role until 1979. Dropsie College remained at the Broad and York complex following Mikveh Israel's departure. A 1981 fire damaged part of Dropsie College's building and the school eventually relocated to
Temple Adath Israel in Merion in 1984. The complex was sold to a church, which did little to rehabilitate the fire-damaged building. The organization Food for Life purchased the complex in November 1992 for $275,000 from the church. The 2321 N Broad Street building was sold for $825,000 in 2015, and was open to the public as a retail clothing store in 2017. ==44 N Fourth Street, 1976–present==
