Andrew "Rube" Foster (September 17, 1879 - December 9, 1930) was an American baseball player, manager, and executive in the Negro leagues. He was elected to the Baseball Hall of Fame in 1981. Foster, considered by historians to have been perhaps the best African-American pitcher of the first decade of the 1900s, also founded and managed the Chicago American Giants, one of the most successful black baseball teams of the pre-integration era. Most notably, he organized the Negro National League, the first long-lasting professional league for African-American ballplayers, which operated from 1920 to 1931.
Foster was born in Calvert, Texas on September 17, 1879. His father, also named Andrew, was a reverend and elder of the local American Methodist Episcopal Church. Foster started his professional career with the Waco Yellow Jackets, an independent black team, in 1897. Over the next few years he gradually built up a reputation among white and black fans alike, until he was signed by Frank Leland's Chicago Union Giants, a team in the top ranks of black baseball, in 1902. After a slump, he was released, and signed with a white semipro team based in Otsego, Michigan - Bardeen's Otsego Independents. According to Phil Dixon's American Baseball Chronicles: Great Teams, The 1905 Philadelphia Giants, Volume III "In completing the summer of 1902 with Otsego's multi-ethnic team--the only multi-race team with which he would ever regularly perform--Foster is reported to have pitched twelve games. He finished with a documented record of eight wins and four loses along with eighty-two documented strikeouts. Ironically, strikeout totals for five games which he appeared were not recorded. If found the totals would likely show that Foster struck out more than one-hundred batters for Otsego. In the seven games where details exist, Foster average eleven strikeouts per outing." Toward the end of the season he joined the Cuban X-Giants of Philadelphia, perhaps the best team in black baseball. The 1903 season saw Foster establish himself as the X-Giants' pitching star. In a post-season series for the eastern black championship, the X-Giants defeated Sol White's Philadelphia Giants five games to two, with Foster himself winning four games. According to various accounts, including his own, Foster acquired the nickname "Rube" after defeating star Philadelphia Athletics left-hander Rube Waddell in a postseason exhibition game played sometime between 1902 and 1905. A newspaper story in the Trenton (NJ) Times from July 26, 1904, contains the earliest known example of Foster being referred to as "Rube", indicating that the supposed meeting with Waddell must have taken place earlier than that. Recent research has uncovered a game played on August 2, 1903, in which Foster met and defeated Waddell while the latter was playing under an assumed name for a semi-pro team in New York City. Now a star, Foster jumped to the Philadelphia Giants for the 1904 season. Legend has it that John McGraw, manager of the New York Giants, hired Foster to teach the young Christy Mathewson the "fadeaway", or screwball, though historians have cast this story in doubt. During the 1904 season, Foster won 20 games against all competition (including two no-hitters) and lost six. In a rematch with Foster's old team, the Cuban X-Giants, he won two games and batted .400 in leading the Philadelphia Giants to the black championship. In 1905, Foster (by his own account several years later) compiled a fantastic record of 51-4, though recent research has confirmed only a 25-3 record. He led the Giants to another championship series victory, this time over the Brooklyn Royal Giants. The Philadelphia Telegraph wrote that "Foster has never been equalled in a pitcher's box." The following season, the Philadelphia Giants helped form the International League of Independent Professional Ball Players, composed of both all-black and all-white teams in the Philadelphia and Wilmington, Delaware, areas.

When did he leave Texas?

he was signed by Frank Leland's Chicago Union Giants, a team in the top ranks of black baseball, in 1902.

William John Evans ( , August 16, 1929 - September 15, 1980) was an American jazz pianist and composer who mostly worked in a trio setting. Evans' use of impressionist harmony, inventive interpretation of traditional jazz repertoire, block chords, and trademark rhythmically independent, "singing" melodic lines continue to influence jazz pianists today. Born in Plainfield, New Jersey, in 1929, he was classically trained, and studied at Southeastern Louisiana University and the Mannes School of Music, where he majored in composition and received the Artist Diploma. In 1955, he moved to New York City, where he worked with bandleader and theorist George Russell.
Evans' career began just before the rock explosion in the 1960s. During this decade, jazz was swept in a corner, and most new talents had few opportunities to gain recognition, especially in America. However, Evans believed he had been lucky to gain some exposure before this profound change in the music world, and never had problems finding employers and recording opportunities. Evans never embraced new music movements; he kept his style intact. For example, he lamented watching Davis shift his style towards jazz fusion, and blamed the change on considerations of commerce. Evans commented "I would like to hear more of the consummate melodic master [Davis], but I feel that big business and his record company have had a corrupting influence on his material. The rock and pop thing certainly draws a wider audience. It happens more and more these days, that unqualified people with executive positions try to tell musicians what is good and what is bad music." However, Evans and Davis kept in touch throughout their lives. While Evans considered himself an acoustic pianist, from the 1970 album From Left to Right on, he also released some material with Fender-Rhodes piano intermissions. However, unlike other jazz players (e.g. Herbie Hancock) he never fully embraced the new instrument, and invariably ended up returning to the acoustic sound. "I don't think too much about the electronic thing, except that it's kind of fun to have it as an alternate voice. (...) [It's] merely an alternate keyboard instrument, that offers a certain kind of sound that's appropriate sometimes. I find that it's a refreshing auxiliary to the piano--but I don't need it (...) I don't enjoy spending a lot of time with the electric piano. I play it for a period of time, then I quickly tire of it, and I want to get back to the acoustic piano." He commented that electronic music: "just doesn't attract me. I'm of a certain period, a certain evolution. I hear music differently. For me, comparing electric bass to acoustic bass is sacrilege."

What was his most promient veiw?
It happens more and more these days, that unqualified people with executive positions try to tell musicians what is good and what is bad music.
