In a statement, Lesser's daughter, Michele Lesser, said, "Heaven got a great comedian and actor today. ... Thank you to all the people who helped make my father's last journey special, and surrounded with love. The doctors, nurses, and staff have been outstanding, and Dad was in phenomenal hands. His passing was peaceful, with great dignity, and surrounded by those who loved him dearly."
