He was also a Buddhist monk!

In 1934, he began studying at the Society of Oxford Home Students at the University of Oxford and became captain of the women’s rowing team. After graduation, he started working in a laboratory near Bristol. Around this time, Dillon became aware of a doctor who had been studying the effects of testosterone on female patients, and started taking the hormone for personal use, driven by a desire to become a man. Dillon left his job at the laboratory after he was outed to his colleagues. He subsequently found a job as a petrol pump attendant in a garage in Bristol and worked there during World War II. Whilst at the garage, he began writing what would become his 1946 book Self: A Study in Ethics and Endocrinology, considered to be a pioneering work in the field of transgender medicine. He also received a gender-affirming double mastectomy whilst in hospital for hypoglycemia and heard of the work of surgeon Sir Harold Gillies, who agreed to perform a phalloplasty on Dillon after the war.
