Arizona's  only Hispanic governor, Raul Castro, has died at age 98. Castro passed away on Friday morning while in his sleep in San Diego where he was in hospice care, family spokesman James Garcia said. He was a self-made man, the embodiment of the American dream overcoming poverty and discrimination to graduate from college, and launch a successful career in politics and diplomacy. During his career, Castro also served as an American ambassador to three countries including El Salvador, Bolivia and Argentina. Arizona Governor Doug Ducey said Castro 'lived a full life of exemplary service to Arizona and its people.' Raul Hector Castro (above pictured in 2006), former governor of Arizona died on Friday morning . 'He was an honorable public servant, a history-maker, a beloved family man and a strong friend and fighter for Arizona,' Ducey said in a statement. Castro is survived by his wife, Pat  and his two daughters, Mary Pat James and Beth Castro, according to AZ Central. Growing up on the US-Mexico border near Douglas, Arizona, Castro saw discrimination around him.

'America is the land of opportunity,' he told The Associated Press in 2010. 'Here, one can accomplish whatever they want to be. But you've got to work for it.' He said he wondered why the Hispanics were laborers and none delivered the mail or worked in offices. It did not seem right that the Hispanic children had to walk miles to school every day while the white kids would wave from a passing school bus, he said. Castro set out to beat the odds. When he could not get a job as a teacher — schools did not hire educators of Mexican descent back then — he became a drifter for a while, working as a farm hand and boxing here and there. He landed a job with the U.S. Consulate in the border city of Agua Prieta, Mexico. After five years, a senior official told him he was doing a great job but had no future in the foreign service — he had a Hispanic name and no Ivy League education. Castro then quit and moved to Tucson. A law school dean at the University of Arizona told Castro he would not be accepted because he could not afford to quit a job teaching Spanish. Besides, the dean said, Hispanic students did not do well in law school. Undeterred, Castro went to the university president, who convinced the dean to give Castro an opportunity to prove himself. Castro died in his sleep in San Diego where he was in hospice care, a family spokesman said (above Castro pictured far right in 1976 with governors at the time including Dick Lamm for Colorado, Jerry Apodaca for New Mexico . He excelled and went on to be elected the first Hispanic county attorney and later the first Hispanic judge in Pima County Superior Court. 'One of the finest men I ever knew,' former Gov. Rose Mofford, a fellow Democrat, said of Castro during a 2010 interview with the AP. Born in Cananea, Mexico, in 1916, some 50 miles south of Arizona, Castro grew up in Arizona and graduated from Douglas High School. He was the second youngest in a family with 12 children — 11 boys and one girl. His father was a union leader forced out of Mexico for organizing a strike at the mine in Cananea. His father died when Castro was 12, and his mother became a midwife to feed the family. She delivered babies for the Mexican families around Douglas in exchange for flower, corn, beans and other staples. Castro serve as U.S. ambassador to El Salvador, Argentina and Bolivia . Education was the best way out, Castro was determined. He went on to serve as U.S. ambassador to three Latin American countries under three U.S. presidents. Lyndon Johnson sent him to El Salvador, where Castro became known as 'Yankee Castro' to differentiate him from the other Raul Castro — the brother of Cuban dictator Fidel Castro. Johnson later sent him to Bolivia and he stayed for a short time under Richard Nixon before returning to Arizona and making the first of two bids for governor. His statewide races were two of the closest gubernatorial elections in state history. He lost to Republican Jack Williams in 1970 by 1.5 percentage points. He fared better four years later as the Republican Party was embroiled in the Watergate corruption scandal. Castro defeated Republican Russ Williams by less than one percentage point three months after Nixon resigned in controversy. As an ambassador and judge, Castro was used to having unquestioned authority. However, he struggled to adjust to the checks and balances imposed on a governor, said Alfredo Gutierrez, a Democrat and legislative leader while Castro was governor. 'It was a very difficult beginning for him,' Gutierrez said. 'It was quite an adjustment.' Castro was governor for two and a half years before resigning when President Jimmy Carter appointed him ambassador to Argentina. He told the AP he was proud of his work motivating Hispanics to vote, many of them for the first time despite deep nerves. 'The thing that bothered me the most when I resigned as governor, the Hispanic community felt that I had betrayed them, because they worked so hard to get me elected,' he said decades later. 'I had to convince them and persuade them that being an American ambassador was just as important as being a governor. I had more authority.' Castro spent his waning years living in Nogales and talking to students around the state, motivating them to work hard and chase lofty dreams.
