Today's birthday girl--born today in 1884--would've had no problem starting conversations at cocktail parties. She was not only Glinda the Good With in The Wizard of Oz, but also the wife of Florence Ziegfeld, Jr. of Ziegfeld Follies.
Her party conversation partners may also have recognized her from her CBS radio program The Billie Burke Show. Whereas throughout the history of American comedy in any medium it's been commonplace for humor to center around the characters' vices and the trouble their machinations get them into, Burke's character on this sitcom was funny while being generous and caring. Episodes often centered around her helping someone but making delightful gaffes along the way.
So here's to Billie Burke, the talented actress with the radiant voice.
