The London School of Jewish Studies (LSJS; founded as Jew's College) is a London-based organisation providing adult educational courses and training to the wider Jewish community. Since 2012 LSJS also offers rabbinical training, returning to its roots. Many leading figures in British Jewry have been associated with the School, including Michael Friedländer, Principal from 1865 to 1907; Isidore Epstein, Principal 1948–1961; Louis Jacobs, Moral Tutor 1959–1961; and in recent years Jonathan Sacks, Principal 1984–1990. In its modern era it has retained the support of the Orthodox Chief Rabbi, Lord Sacks, who stated that: "LSJS is part of a treasured tradition more valuable than jewels and more enduring than any precious metal. That is why my deepest commitment to any institution in Anglo-Jewry is to LSJS".
The London School of Jewish Studies was founded as Jews' College in 1855, a rabbinical seminary in London. The organisation was re-focussed and given its present name in 1999, with an emphasis on providing a broader range of adult educational courses and training to the wider Jewish community. The rabbinical training programme was suspended, and much of the historical holdings of the library were sold off. LSJS has had growing success in its new role, and since 2012 once again offers rabbinical training, in partnership with the programme set up by the London Sephardi community.
Jews' College was opened in Finsbury Square, London as a rabbinical seminary in 1855 with the support of Chief Rabbi Nathan Adler and of Sir Moses Montefiore, who had conceived the idea for such a venture as early as 1841. The college quickly established itself as a place where high quality rabbinical training was available and its alumni and staff often became prominent in Anglo-Jewry.
In 1881, the College moved to larger premises in , close to University College, where it was envisaged that Jews’ College students would be able to combine their religious studies and university studies to degree level. As early as 1904, the University of London granted an Honours degree in Hebrew and Aramaic, all of the candidates being from Jews’ College. In 1932, with the building of Woburn House, a centre for Anglo-Jewry, still in Tavistock Square, Jews' College moved again.
