Richard (Dick) Claxton Gregory was a comedian, civil rights and animal rights and vegan activist. Gregory became popular among the African-American communities in the southern United States with his "no-holds-barred" sets, poking fun at the bigotry and racism in the United States. In 1961 he became a staple in comedy clubs, appeared on national television and released comedy record albums. Gregory was at the forefront of political activism in the 1960s, when he protested against the Vietnam War and racial injustice. He was arrested multiple times and went on many hunger strikes. He later became a speaker and author. He said: " Because I'm a civil rights activist, I am also an animal rights activist. Animals and humans suffer and die alike. Violence causes the same pain, the same spilling of blood, the same stench of death, the same arrogant, cruel and vicious taking of life. We shouldn't be a part of it."

While he was described as a religious skeptic, it doesn't seem that he held a naturalistic worldview. He said "I am god, you are god." He often talked of spirituality and supported a number of poorly-evidenced conspiracy theories.
