How did Pete Seeger get his name?

Pete Seeger was born Peter Seeger.

The Almanac Singers, which Seeger co-founded in 1941 with Millard Lampell and Arkansas singer and activist Lee Hays, was a topical group, designed to function as a singing newspaper promoting the industrial unionization movement, racial and religious inclusion, and other progressive causes. As a controversial Almanac singer, the 21-year-old Seeger performed under the stage name "Pete Bowers" to avoid compromising his father's government career. Later in his career, he used the stage name Pete Seeger.
