The founding father of the USA who can be said to be the founder of American biological criminology is D. Benjamin Rush.
He was a physician and signer of the Declaration of Independence who believed that criminal behavior could be traced to physical abnormalities in the brain and body.
He argued that crime was not simply a moral failing, but rather a medical condition that required treatment. Rush's views on biological criminology were influential in shaping early debates about the causes of crime in America.
