John Wren

Power Without Glory In 1950, the novelist Frank Hardy portrayed Wren negatively in his self-published 1950 novel Power Without Glory, in which Wren appears thinly disguised as a character called John West. The book also included characters based on other important Victorian and Australian political figures, including Victorian Premier Sir Thomas Bent and Prime Minister James Scullin, as well as Roman Catholic Archbishop Daniel Mannix. Due to the fact that Hardy was a member of the Communist Party of Australia, the book, and its criticisms of Wren, became politically embroiled in the anti-communist culture of the Cold War. John Wren's wife, Ellen Wren, sued Hardy for libel after the book's publication.

Other books about John Wren Frank Brennan's son, the author Niall Brennan, gave a favourable portrayal of Wren in his 1971 biography, John Wren: Gambler. Hugh Buggy's The Real John Wren (1977), with a foreword by Arthur Calwell, Federal Parliamentary Labor Party Deputy Leader, was also very favourable. An alternative account was given by Chris McConville's article in Labor History, "John Wren: Machine Boss" (1981). John Wren: A Life Reconsidered by James Griffin (2004) presented an essentially positive view of Wren's life and career.

Family Wren's granddaughter Gabrielle Pizzi also achieved renown as an art dealer credited with raising the profile of Aboriginal art. Others of his children had troubled lives. His son Anthony committed suicide after being disinherited following an argument with Wren, while his daughter-in-law Nora and grandchildren only received a meagre allowance. When another of Wren's grandchildren, Susan Wardlaw, died, her two brothers had her buried without notifying her husband Greg, who was then given 24 hours to leave the family home, while another of Wren's daughters, Angela, purportedly died of malnutrition when she was 39, leaving an estate worth £97,000.

Collingwood benefactor Wren was well known for supporting exemplary Collingwood players in the VFL's pre-professionalised era. While players were paid a per-game salary, the amount was meagre until the late 20th century when the sport became professionalised. To compensate for this, Wren was known to send monetary gifts to players who performed well, often paying ten to twenty times the normal game salary to certain Collingwood players. Among the beneficiaries included Collingwood legend Gordon Coventry after he scored a then-record 16 goals in a game in 1929; however, in his case, League Laws prevented him from doing this, so he exploited a loophole by gifting A£50 to Coventry's wife (A$ in terms) to buy a suite of furniture.

In 1952, Wren donated A£500 (A$ in terms), which was to be distributed among Collingwood players.

In another example of generosity, Lou Richards recalled on The Sunday Footy Show a time when Wren asked Richards how much he was paid the week prior. When Richards replied "a pound note, sir", Wren gifted Richards A£20 (potentially up to A$ in terms, as the year this happened was not clarified).
