May Ruth Snyder was an American murderer. Her execution in the electric chair at New York's Sing Sing Prison in 1928 for the murder of her husband, Albert Snyder, was recorded in a highly-publicized photograph.

The electric chair is a specialized device employed for carrying out capital punishment through the process of electrocution. During its use, the individual sentenced to death is securely strapped to a specially designed wooden chair and electrocuted via strategically positioned electrodes affixed to the head and leg. This method of execution was conceptualized by Alfred P. Southwick, a dentist based in Buffalo, New York, in 1881. Over the following decade, this execution technique was developed further, aiming to provide a more humane alternative to the conventional forms of execution, particularly hanging. The electric chair was first utilized in 1890 and subsequently became known as a symbol of this method of execution.
