William Cowherd

William Cowherd (1763 – 1816) was a Christian minister serving a congregation in the City of Salford, England, immediately west of Manchester, and one of the philosophical forerunners of the Vegetarian Society founded in 1847. Cowherd advocated and encouraged members of his then small group of followers, known as Cowherdites to abstain from the eating of meat as a form of temperance.

After teaching philology at Beverley Cowherd came to Manchester and became curate to the Rev John Clowes at St John's Church. Having studied the writings of Emanuel Swedenborg, he like Clowes, adopted Swedenborgian doctrine and preached at the Swedenborgian church in Peter Street. He is said to have been the only man to read the Latin writings of Swedenborg in their entirety.

In 1800 Cowherd established a new congregation in Salford, building the chapel at his own expense. His chapel, Christ Church, was located in King Street, Salford, just across the River Irwell from Manchester. Believing that ministers should maintain themselves he conducted a school and practised as a physician from time to time. In 1809 he promulgated the doctrine that people should "eat no more meat till the world endeth" and abstain from alcoholic drinks.

The denomination he founded was known as the Bible Christian Church (not to be confused with Methodist sect of the same name based in the South-west of England). His early ideas and insight into the abstinence from eating meat, provided the basis for early ideas about vegetarianism. The message was preached in the U.S. when 41 members of the Bible Christian Church crossed the Atlantic in 1817.

Cowherd is credited with being the main figure advocating the theory of vegetarianism. It is noted that he asked his congregation in a sermon preached on January 18, 1809, to refrain from eating meat which culminated in the founding of the Vegetarian Society in 1847.
