Pete Seeger, one of the most influential artists in American history, would be 100 on May 3, were he still alive.

Pete provided much of the soundtrack for the political awakening of several generations of activists. The songs he wrote, including the antiwar tunes, “Where Have All the Flowers Gone?” “If I Had a Hammer” and “Turn, Turn, Turn,” and those he has popularized, including “This Land Is Your Land” and “We Shall Overcome,” have been recorded by hundreds of artists in many languages and have become global anthems for people fighting for freedom. He introduced Americans to songs from other cultures, like “Wimoweh” (“The Lion Sleeps Tonight”) from South Africa, “Tzena, Tzena” from Israel (which reached number two on the pop charts), and “Guantanamera” from Cuba, inspiring what is now called “world music.”

Thanks to Seeger’s influence, protest songs — via folk, rock, blues, and soul genres — became popular and even commercially successful. He recorded over eighty albums — of children’s songs, labor, civil rights, and antiwar songs, traditional American folk songs, international songs, and Christmas songs. Among performers around the globe, Seeger became a symbol of a principled artist deeply engaged in the world.
