Biography
Robert Elliott O'Callaghan was born in St Pancras, London, in December 1855, of Irish Catholic descent. His attention was first directed to vegetarianism by one of Francis William Newman's lectures, a report of which he noticed in a shop window. In 1880, he joined the London Food Reform Society and became a member of its Executive the following year. O'Callaghan gained recognition for his effective lectures on vegetarianism, often enhanced with illustrations using a magic lantern.

O'Callaghan held several significant positions within the vegetarian movement. He served as the official lecturer for the Vegetarian Association, the secretary of the London Vegetarian Society, and, from 1890, as the First Secretary of the Vegetarian Federal Union. He later acted as an agent for the Federal Union for the Southern Counties.

In 1888, O'Callaghan married Mary Ann Barry in Fulham, and the couple had one daughter, Florence. He became the proprietor of the London vegetarian restaurant, the Wheat Sheaf, located at 13 Rathbone Place, Oxford Street, taking over from Mrs. Britton.

O'Callaghan authored several publications on vegetarianism. In 1889, he published The Best Diet for a Working Man. The following year, he co-authored The Manual of Vegetarianism: A Complete Guide to Food Reform with Charles W. Forward. This was followed by The Diet of Health & Happiness in 1893 and How to Begin Vegetarianism with Month's Dietary and Cookery Book.  He also published a pamphlet, The Testimony of Science Against Flesh Eating.

In 1900, O'Callaghan founded the Catholic Humane League, aimed at promoting humane principles among Catholics in line with the teachings of the Church. He served as its Honorary Secretary.

O'Callaghan later moved to Manchester with his family and worked as the secretary of a philanthropy society. He died there in December 1936 at the age of 81. He was buried three days later in the Southern Cemetery.
