Leonard previously announced via Twitter that he had been diagnosed with COPD, which he attributed to his past years of smoking. He had been hospitalized late last week with severe chest pains.
The star's film and television acting career began in 1951 when he landed the title role in the 1952 film 'Kid Monk Baroni.' In the years following, Leonard scored several supporting parts in movies and popular TV shows including 'Perry Mason' and 'Dragnet.'
