Geoffrey Alderman (born 10 February 1944) is a British historian, especially of the Jewish community in England in the 19th and 20th centuries, and also an academic, political adviser and journalist.
Born in Middlesex, Alderman studied history at Lincoln College, Oxford from 1962, gaining his BA in 1965 and an MA and D.Phil. in 1969. After short academic contracts at University College London, and the universities of Swansea and Reading he joined Royal Holloway College (University of London) in 1972, lecturing in politics and contemporary history. He was made Professor of Politics and Contemporary History in 1988.
From 1989 to 1994 he held senior administrative posts in the University of London and from 1994 to 1999 in Middlesex University. From 1999 he has worked in the private educational sector, in the US (Touro College) and, from 2002 to 2006, at the American InterContinental University, London, where he was Academic Dean and Senior Vice-President. On 1 June 2007 Alderman joined the University of Buckingham.
In 2010 he was appointed a Visiting Fellow of the Oxford Centre for Higher Education Policy Studies.
At a ceremony in London on 6 March 2011 Alderman was named as the winner of the Chaim Bermant Prize for Journalism 2011.
He describes himself as an unconventional Orthodox Jew.
Naomi Alderman, Geoffrey Alderman's daughter, was the author of the winning novel of the 2006 Orange Award for New Writers with Disobedience.
Judaism and origins of Islam
Alderman's comments in an article published in The Jewish Chronicle, drew criticism from some civil rights groups[who?] as Alderman accused Islam of being founded "in part, on an explicit anti-Jewish discourse."
Higher education in Britain
In the summer of 2008, following his inaugural professorial lecture at the University of Buckingham, and criticisms of some aspects of UK higher education by the UK Quality Assurance Agency for Higher Education, a brief parliamentary inquiry was undertaken into these allegations. At that inquiry (17 July 2008) the chairman of the House of Commons' Select Committee on Innovation, Universities and Skills accused the Quality Assurance Agency of being "toothless" and declared that the British degree classification system had "descended into farce". Alderman himself gave written  and oral evidence to a subsequent enquiry of the Select Committee into Students and Universities, whose report (2 August 2009) included an endorsement of Alderman's views.
Haredi sexual harassment
In early 2012, the Jewish Chronicle reported that complaints were made against a column by Alderman in which he wrote that "it is well known that Charedi men are notorious harassers of the opposite sex", that these comments breached accuracy and discrimination rules. The Press Complaints Commission rejected these complaints because it was clear to readers that the content was written from Alderman's own perspective and whether or not the article was offensive requires subjective judgement. 
Of his dozen or so books, the best-known is Modern British Jewry (second edition, 1998, OUP). He has also written for the New Dictionary of National Biography, with special responsibility for post-1800 Jewish entries, and for The Guardian and The Jewish Chronicle.
