Thomas Richard Allinson (29 March 1858 – 29 November 1918) was an English physician, dietetic reformer, businessman, journalist and vegetarianism activist.

In 1911, Allinson bought the failing magazine Vanity Fair from Frank Harris.

Although it has been claimed that Allinson was offered the right to re-register during WW1, the General Medical Council has no record of this and by that time he had no registrable qualifications.

After his death, the company grew: two more stone-grinding mills were purchased in Newport, Monmouthshire and in 1921 Castleford, Yorkshire.

[8] In place of orthodox medicine, he promoted health through diet, exercise, fresh air and bathing.

He opposed the use of drugs by doctors, many of which at that time were ineffective and toxic and was a lifelong opponent of compulsory vaccination against smallpox.

To demonstrate the suitability of a vegetarian diet for strenuous exercise, he undertook a walk from Edinburgh to London in 1891.

Mahatma Gandhi, who was studying law in Britain at the time and was also a member of the Vegetarian Society, spoke in favour of Allinson's right to support contraception, despite being opposed to it.

[7] In 1893, Allinson sued the Vegetarian newspaper for alleged libel as an article had been published with a comment that his theories encouraged sexual immorality.
