Stan Kenton was born on December 15, 1911 in Wichita, Kansas; he also had two sisters (Beulah and Erma Mae) born three and eight years after him. His parents, Floyd and Stella Kenton, had moved the family back to Colorado, then, finally in 1924 to the Greater Los Angeles Area, settling in suburban Bell, California. Kenton attended Bell High School; his high school yearbook picture has the prophetic notation "Old Man Jazz". Kenton started learning piano as a teen from a local pianist and organist.
In April 1936 Gus Arnheim was reorganizing his band into the style of Benny Goodman's groups and Kenton was to take the piano chair. This is where Kenton would make his first recordings when Arnheim made 14 sides for the Brunswick label in summer of 1937. Once he departed from Gus Arnheim's group, Kenton went back to study with private teachers on both the piano and in composition. In 1938 Kenton would join Vido Musso in a short-lived band but a very educational experience for him. From the core of this group come the line up of the first Stan Kenton groups of the 1940s. Kenton would also go on to working with the NBC House Band and in various Hollywood studios and clubs. Producer George Avakian took notice of Kenton during this time while he worked as the pianist and Assistant Musical Director at the Earl Carroll Theatre Restaurant in Hollywood. Kenton started to get the idea of running his own band from this experience; he created a rehearsal band of his own which eventually become his group in the 1940s. In June 1941, Kenton formed his first orchestra. Kenton worked in the early days with his own groups as much more of an arranger than a featured pianist. Although there were no "name" musicians in his first band (with the possible exception of bassist Howard Rumsey and trumpeter Chico Alvarez), Kenton spent the summer of 1941 playing regularly before an audience at the Rendezvous Ballroom in Balboa Beach, CA. Influenced by Benny Carter and Jimmie Lunceford, the Stan Kenton Orchestra struggled for a time after its initial success. Its Decca recordings were not big sellers and a stint as Bob Hope's backup radio band during the 1943-44 season was an unhappy experience; Les Brown permanently took Kenton's place. Kenton's first appearance in New York was in February 1942 at the Roseland Ballroom, with the marquee featuring an endorsement by Fred Astaire. By late 1943, with a contract with the newly formed Capitol Records, a popular record in "Eager Beaver", and growing recognition, the Stan Kenton Orchestra was gradually catching on; it developed into one of the best-known West Coast ensembles of the 1940s. Its soloists during the war years included Art Pepper, briefly Stan Getz, altoist Boots Mussulli, and singer Anita O'Day. By 1945, the band had evolved. The songwriter Joe Greene provided the lyrics for hit songs like "And Her Tears Flowed Like Wine" and "Don't Let the Sun Catch You Cryin'". Pete Rugolo became the chief arranger (extending Kenton's ideas), Bob Cooper and Vido Musso offered very different tenor styles, and June Christy was Kenton's new singer; her hits (including "Tampico" and Greene's "Across the Alley from the Alamo") made it possible for Kenton to finance his more ambitious projects.

How long did he stay with Gus Arnheim?

1937.

Answer the question at the end by quoting:

Caesar was the youngest of three sons born to Jewish immigrants living in Yonkers, New York. His father was Max Ziser (1874-1946) and his mother was Ida (nee Raphael) (1887-1975). They likely were from Dabrowa Tarnowska, Poland. Reports state that the surname "Caesar" was given to Max, as a child, by an immigration official at Ellis Island.
After graduating from Yonkers High School in 1939, Caesar left home, intent on a musical career. He arrived in Manhattan and worked as an usher and then a doorman at the Capitol Theater there. He was ineligible to join the musicians' union in New York City until he established residency, but he found work as a saxophonist at the Vacationland Hotel, a resort located in the Catskill Mountains of Sullivan County, New York. Mentored by Don Appel, the resort's social director, Caesar played in the dance band and learned to perform comedy, doing three shows a week. He audited classes in clarinet and saxophone at the Juilliard School of Music. In 1939, he enlisted in the United States Coast Guard, and was stationed in Brooklyn, New York, where he played in military revues and shows. Vernon Duke, the composer of Autumn in New York, April in Paris, and Taking a Chance on Love, was at the same base and collaborated with Caesar on musical revues. During the summer of 1942, Caesar met his future wife, Florence Levy, at the Avon Lodge in the Catskills village of Woodridge, New York. They were married on July 17, 1943, and had three children: Michele, Rick and Karen. After joining the musicians' union, he briefly played with Shep Fields, Claude Thornhill, Charlie Spivak, Art Mooney and Benny Goodman. Later in his career, he performed "Sing, Sing, Sing" with Goodman for a TV performance. Still in the service, Caesar was ordered to Palm Beach, Florida, where Vernon Duke and Howard Dietz were putting together a service revue called Tars and Spars. There he met the civilian director of the show, Max Liebman. When Caesar's comedy got bigger applause than the musical numbers, Liebman asked him to do stand-up bits between the songs. Tars and Spars toured nationally, and became Caesar's first major gig as a comedian. Liebman later produced Caesar's first television series. After the war, the Caesars moved to Hollywood. In 1946, Columbia Pictures produced a film version of Tars and Spars in which Caesar reprised his role. The next year, he acted in The Guilt of Janet Ames. He turned down the lead of The Jolson Story as he did not want to be known as an impersonator, and turned down several other offers to play sidekick roles. He soon returned to New York, where he became the opening act for Joe E. Lewis at the Copacabana nightclub. He reunited with Liebman, who guided his stage material and presentation. That job led to a contract with the William Morris Agency and a nationwide tour. Caesar also performed in a Broadway revue, Make Mine Manhattan, which featured The Five Dollar Date--one of his first original pieces, in which he sang, acted, double-talked, pantomimed, and wrote the music. He won a 1948 Donaldson Award for his contributions to the musical.
