Harry Lillis "Bing" Crosby (May 3, 1903 – October 14, 1977) was an American popular singer and actor whose career stretched over more than half a century from 1926 until his death.

One of the first multimedia stars, from 1934 to 1954 Bing Crosby held a nearly unrivaled command of record sales, radio ratings and motion picture grosses. Widely recognized as one of the most popular musical acts in history, Crosby is also credited as being the major inspiration for most of the male singers of the era that followed him, including Frank Sinatra, Perry Como, and Dean Martin

Music
In 1926, while singing at Los Angeles Metropolitan Theater, Crosby and his vocal duo partner Al Rinker caught the eye of Paul Whiteman, arguably the most famous bandleader at the time. Hired for $150 a week, they made their debut on December 6, 1926 at the Tivoli Theatre (Chicago). Their first recording, "I've Got The Girl," with Don Clark's Orchestra, was issued by Columbia and did them no vocal favors as it sounded as if they were singing in a key much too high for them. It was later revealed that the 78rpm was recorded at a speed slower than it should have been, which increased the pitch when played at 78rpm.

As popular as the Crosby and Rinker duo was, Whiteman added another member to the group, pianist and aspiring songwriter Harry Barris. Whiteman dubbed them The Rhythm Boys, and they joined the Whiteman vocal team, working and recording with musicians Bix Beiderbecke, Jack Teagarden, Tommy Dorsey, Jimmy Dorsey, and Eddie Lang and singers Mildred Bailey and Hoagy Carmichael.

Crosby soon became the star attraction of the Rhythm Boys, not to mention Whiteman's band, and in 1928 had his first number one hit, a jazz-influenced rendition of "Ol' Man River." However, his repeated youthful peccadilloes and growing dissatisfaction with Whiteman forced him, along with the Rhythm Boys, to leave the band and join the Gus Arnheim Orchestra. During his time with Arnheim, The Rhythm Boys were increasingly pushed to the background as the vocal emphasis focused on Crosby. Fellow member of The Rhythm Boys Harry Barris wrote several of Crosby's subsequent hits including "At Your Command," "I Surrender Dear," and "Wrap Your Troubles In Dreams"; however, shortly after this, the members of the band had a falling out and split, setting the stage for Crosby's solo career. In 1931, he signed with Brunswick Records and recording under Jack Kapp and signed with CBS Radio to do a weekly 15 minute radio broadcast; almost immediately he became a huge hit.

As the 1930s unfolded, it became clear that Bing was the number one man, vocally speaking. Ten of the top 50 songs for 1931 either featured Crosby solo or with others. Apart from the short-lived "Battle of the Baritones" with Russ Columbo, "Bing Was King," signing long-term deals with Jack Kapp's new record company Decca and starring in his first full-length features, 1932's The Big Broadcast, the first of 55 such films in which he received top billing. He appeared in 79 pictures.

Around this time Crosby made his solo debut on radio, co-starring with The Carl Fenton Orchestra on a popular CBS radio show, and by 1936 replacing his former boss, Paul Whiteman, as the host of NBC's Kraft Music Hall, a weekly radio program where he remained for the next ten years. As his signature tune he used "Where the Blue of the Night (Meets the Gold of the Day)", which also showcased his whistling skill.

He was thus able to take popular singing beyond the kind of "belting" associated with a performer like Al Jolson, who had to reach the back seats in New York theatres without the aid of the microphone. With Crosby, as Henry Pleasants noted in The Great American Popular Singers, something new had entered American music, something that might be called "singing in American," with conversational ease. The oddity of this new sound led to the epithet "crooner."

Crosby gave great emphasis to live appearances before American troops fighting in the European Theater. He also learned how to pronounce German from written scripts and would read them in propaganda broadcasts intended for the German forces. The nickname "der Bingle" for him was understood to have become current among German listeners, and came to be used by his English-speaking fans. In a poll of U.S. troops at the close of WWII, Crosby topped the list as the person who did the most for G.I. morale, beating out President Franklin Delano Roosevelt, General Dwight Eisenhower, and Bob Hope.

Crosby's biggest musical hit was his recording of Irving Berlin's "White Christmas", which he introduced through a 1942 Christmas-season radio broadcast and the movie Holiday Inn. Crosby's recording hit the charts on October 3, 1942, and rose to #1 on October 31, where it stayed for 11 weeks. In the following years, his recording hit the Top 30 pop charts another 16 times, topping the charts again in 1945 and January 1947. The song remains Crosby's best-selling recording, and the best-selling single and best-selling song of all time. In 1998, after a long absence, his 1947 version hit the charts in Britain, and as of 2006 remains the North American holiday-season standard. According to Guinness World Records, Crosby's recording of "White Christmas" has "sold over 100 million copies around the world, with at least 50 million sales as singles."
