Moral Inquiries on the Situation of Man and of Brutes (Revised ed)

Inventor, feminist, humanitarian and founder of the RSPCA, Gompertz argued for a rational morality in our treatment of both humans and animals.

He has been compared with Leonardo and Pythagoras in the range of his abilities and thinking.

Inventor of the expanding chuck and of 37 other recorded devices, many designed to reduce animal suffering, he renounced flesh, eggs, milk, leather and silk, condemned vivisection and would not ride in a horse-drawn coach.

Convinced of "the similitude between man and other animals", his championing of those weaker than ourselves places him high in the history of the humane movement.
