Barbara Feldon is a character actress of both stage and television who
is primarily known for the role of Agent 99 on the popular 1960s sitcom 
Get Smart on NBC and later CBS. Following her first work as a model,
Feldon’s break came in the form of a popular and much parodied TV
commercial (shown below) for "Top Brass," a hair pomade for men.
