Comic and television writer-producer Marty Nadler dies at 80. Multiple outlets report that Nadler, who wrote for and produced sitcoms associated with Garry Marshall, dies on Aug. 26 in Margate, Florida.

His son, Charlie Nadler, tells reporters that Nadler’s death is due to complications from myasthenia gravis. Across coverage, Nadler is described as a stand-up comedian and writer whose television credits include “Happy Days” and “Laverne & Shirley.” Variety also notes additional work on “The Odd Couple,” while Deadline emphasizes his longtime collaborations with Garry Marshall across major sitcoms and his film work.

Both sources agree on the key biographical details: Nadler’s age at death, location and date of death, and the cause as complications from myasthenia gravis. They differ slightly in which specific projects are highlighted and how broadly they frame his film career.
