My late uncle was the famous entertainer Bing Crosby.  My father was Ted Crosby his older brother by three years.  Most people from my generation tend to think of him as the orange juice/Christmas guy, and not for the entertainment giant/pioneer of the 20th century that he truly was.  There is a very good and honest book written by Gary Giddens of the Village Voice "Bing Crosby-A Pocket Full of Dreams"  that chronicles his many contributions to music as well as technology. 

Bing circa 1935, on his way to the top!

*  The most frequently heard voice of the 20th century.

*  Developed the modern style of singing that every singer since him is indebted.

*  Sold more records than Elvis and the Beatles combined.

*  Technological pioneer-instrumental in the development of audio and video tape.

*  The number one box office attraction from 1944-1949, a record never equaled.
