Welwyn in 1943. He studied at
Wadham College, Oxford from 1961, graduating BA in 1965. After working for some time as a civil servant, he studied from 1970 at the
University of Toronto, where he graduated MA in 1971 and obtained his doctorate in 1976. His doctoral thesis, written under the supervision of
Desmond Conacher, was a commentary on the first half of Euripides' tragedy
Heracles. In 1974, he was appointed as a lecturer in classics at the
University of Calgary, Cropp contributed commentaries on
Electra and
Iphigenia in Tauris to the "Aris and Phillips Classical Texts" series of editions of Euripides, edited by
Christopher Collard, in 1988 and 2000, and revised each of these in updated second editions in 2013 and 2023. In collaboration with Collard, Cropp contributed to the Aris and Phillips editions of selected fragmentary plays by Euripides in 1995 and 2004, and co-authored the
Loeb Classical Library edition of the Euripidean fragments in 2008. From 1984 to 1990, Cropp was joint editor of the journal
Échos du monde classique: Classical Views, alongside
John C. Yardley. In 1999, Cropp and
Kevin H. Lee organised a major conference on Euripides at the
Banff Centre west of Calgary, with Desmond Conacher as the guest of honour. This led to the publication in 2000 of a volume of essays,
Euripides and Tragic Theatre in the Late Fifth Century. Cropp was honoured in 2009 with a
Festschrift, titled
The Play of Texts and Fragments: Essays in Honour of Martin Cropp. ==Selected publications==
