Espinosa Chepe, Cuban Dissident Economist, Dies Oscar Espinosa Chepe, a high-level Cuban economist and diplomat who broke with Fidel Castro's government in the 1990s and was imprisoned for dissident activities, died in Spain on Monday. He was 72. Espinosa died in Fuenfria Hospital in Cercedilla, just north of Madrid, where he had been undergoing treatment for chronic liver disease since March. His wife, Miriam Leiva, said she was not sure whether his remains would be repatriated. "We had hoped the disease could be stopped, but it could not be," Leiva said. He always wanted to return to Cuba. Espinosa was one of 75 writers and political activists locked up in 2003 during the Black Spring, a notorious crackdown on dissent that provoked international criticism and EU sanctions lasting five years. Little known at the time of his imprisonment, Espinosa was sentenced to 20 years but released after 19 months on medical humanitarian grounds, on his 64th birthday. By then his name was more familiar in part thanks to the work of Leiva, who helped found the Ladies in White protest group to press for their husbands' release. Espinosa said the government had made a mistake by locking him and the others up, and vowed they would not be silenced. The Cuban government frequently accuses island dissidents of accepting money from Washington to undermine the government, but Espinosa frequently denied being a "mercenary." "We are nonviolent people who have not committed any crime," he told reporters in November 2004 at his and Leiva's tiny Havana apartment, always overflowing with the books, papers and statistical reports they used to write about Cuba's complex and troubled economy. Espinosa had suffered from liver problems for years and in the early 2000s was diagnosed with cirrhosis. He was also hospitalized in August 2012. "My health problems are from before I was imprisoned, but the conditions of the prison contributed to making them worse," Espinosa told The Associated Press shortly before he traveled to Spain for medical treatment. Gray-haired and soft-spoken, "Chepe," as he was commonly called, was known for fixing his gaze firmly on whomever he was talking to and repeatedly adjusting his spectacles as he spoke. He was born Nov. 29, 1940, in the central province of Cienfuegos, and along with many of his generation was infused with revolutionary fervor following Fidel Castro's 1959 Cuban Revolution. He graduated with a degree in economics from the University of Havana in 1961 and began a long career of mid- and high-ranking posts in the government, including as counselor to then-Prime Minister Castro in the '60s and later as head of the powerful Office of Agrarian Reform. Espinosa also was a member of the State Committee for Economic Collaboration, specializing in a handful of Soviet bloc nations, and did a stint as Cuba's economic attache in Yugoslavia. He took up a position at the National Bank of Cuba upon his return in the 1980s, but increasingly found himself at odds with government policy. According to Espinosa's account, in the early 1990s, after voicing disagreement with the country's economic policies, he was denounced by a colleague, publicly sanctioned and ultimately fired. From his later writings, it was clear that Espinosa believed the Communist government wielded excessive control over the economy and he was a strong critic of corruption and bureaucracy.
