Herbert Lionel Matthews (January 10, 1900 – July 30, 1977) was a reporter and editorialist for The New York Times who, at the age of 57, won widespread attention after revealing that the 30-year-old Fidel Castro was still alive and living in the Sierra Maestra mountains. President Fulgencio Batista claimed publicly that the young guerilla leader had been killed during the landing of the yacht Granma, bringing him and others back to Cuba from Mexico in December 1956.
