Not three months ago, on Dec. 31, it was announced that football and television star Merlin Olsen had been diagnosed with mesothelioma. Today I learned that he has passed away, a victim of this horrible disease that lies in wait to kill. He was only 69 years old.

Olsen was a star defensive lineman for the Los Angeles Rams football team, who went on to a television acting career. He played Jonathan Garvey on the series Little House on the Prairie and was the title character of Father Murphy. He also appeared on Fathers and Sons and Aaron’s Way, and filled the role of sportscaster at both CBS and NBC.

Online celebrity news magazine TMZ broke the news in December that Olsen and his family had filed a lawsuit against several companies, including NBC Studios, NBC Universal and 20th Century Fox Film Corporation, claiming they were responsible for exposing him to asbestos, which causes mesothelioma. Also named in the suit are Sherwin Williams and Lennox Industries, whose products Olsen says he was exposed to during jobs in his youth.

Read his obituary in the Los Angeles Times.

On December 8, 2009, his alma mater, Utah State University, where he was selected twice as an NCAA All-American, among other honors, announced it would name its football field after him – Merlin Olsen Field. How truly sad that he will never see a team take the field that now bears his name. Watch the tribute video created by the university at the announcement:

What a sad loss of a man who truly seemed to care genuinely for others, for his family and his community. He will be genuinely missed.

On Dec. 31, the online celebrity news source, TMZ, revealed that football and television star Merlin Olsen has filed a lawsuit against a number of companies, claiming they are responsible for exposing him to asbestos, resulting in his recent diagnosis of malignant mesothelioma. Companies named in the suit are Sherwin Williams and Lennox Industries, whose products Olsen says he was exposed to during jobs in his youth, but also NBC Studios, NBC Universal, and 20th Century Fox Film Corporation. It is unclear from the lawsuit how the television and movie companies contributed to Olsen’s asbestos exposure.

Olsen was a professional football player for the Los Angeles Rams team, and later had a successful career as a sportscaster and actor, most notably on shows “Little House on the Prairie” and “Father Murphy.”

According to the lawsuit, filed in Los Angeles County Superior Court, the defendants “were engaged in the business of manufacturing, fabricating, designing, assembling, distributing, leasing, buying, selling, inspecting, servicing, installing, repairing, marketing, warranting and advertising a certain substance the generic name of which is asbestos.”

News reports say Olsen, with wife Susan by his side, is fighting his mesothelioma and currently undergoing chemotherapy.
