Harris A. Smiler

Harris A. Smiler was among the first four convicts to be executed by electrocution at Sing Sing Prison, in Ossining, New York. 
The electric chair was installed in Sing Sing Prison, in 1891, just a year after it was first used to execute William Kemmler at Auburn Prison, also in New York State. By the end of the 1800s, 29 inmates had been executed by this means. The United States and United Kingdom both began independently tracking murder rate and other crime statistics in earnest at the start of the next century.
