Benjamin Bradley (inventor) Benjamin Bradley was an African American engineer and inventor. Born a slave in Maryland, around 1830, Bradley learned literacy from his Master's children when, at the time, was against the law to teach a slave how to read or write because they would demand rights. Bradley was also good at mathematics, and showed a natural talent for making things. As a teenager, Bradley was put to work at an office where he built a working steam engine from pieces of scrap metal. Others were so impressed with Bradley's mechanical skills that he was given a job as an assistant in the science department at the United States Naval Academy in Annapolis, Maryland where he set up and helped conduct experiments. Professors at the Naval Academy were impressed with Bradley, saying he was smart, a quick learner, and did not make mistakes. Bradley was paid in full for his work, but the money he had made went to his Master, who allowed Bradley to keep five dollars a month for himself.
