History of animal testing
In 1996 Dolly the sheep was born, the first mammal to be cloned from an adult cell. The process by which Dolly the sheep was cloned utilized a process known as nuclear transfer applied by lead scientist Ian Wilmut. Although other scientists were not immediately able to replicate the experiment, Wilmut argued that the experiment was indeed repeatable, given a timeframe of over a year.
Dolly Kay
Details of her life are obscure. She was probably born Dora Kirschenbaum in New York City in 1900. She lived with her parents in Westchester, New York, and worked as a stenographer. According to a "Los Angeles Times" article in 1923, she was so inspired by seeing a vaudeville performance a few years previously that she introduced herself to an agent, who auditioned her and immediately hired her. She began performing as a singer on the Orpheum Circuit, with pianist Phil Phillips, who remained her accompanist for at least the next twenty years.
