Edward Rulloff Genius Serial Killer

Edward H. Rulloff, a 19th-century American serial killer, was also a highly educated polymath who was also a doctor, lawyer, photographer, inventor, schoolmaster, philologist, phrenologist, and carpet designer. After authorities arrested him for murder, Rulloff spent time in jail, where he wrote a scholarly book on the evolution of language and was even allowed to teach students while imprisoned. When he died in 1871 after his execution in Binghamton, New York, scientists examined his body and discovered that his brain was the second largest ever recorded at the time.
