“My Three Sons” star Dawn Lynn, 59, is in a coma after brain surgery

My Three Sons star Dawn Lynn is fighting for her life in a coma after surgery to remove a brain tumour, reports TMZ.

The former child star, now 59, rose to fame as a six-year-old as Dorothy “Dodie” Harper-Douglas in the last three seasons of the CBS sitcom, which she played from 1969-1972.

Dawn’s condition was announced on social media by her former co-stars, including Stanley Livingston (who played Richard “Chip” Douglas) and Tina Cole (who played Kathy Miller-Douglas), and the cast urged fans to “pray” for Dawn’s recovery.

Stanley wrote last week: ‘Just found out my TV little sister’ DAWN LYNN (Dodie) is in a coma and fighting for her life. She recently underwent surgery to remove a brain tumor.

“Please pray for her speedy and full recovery. A couple of months ago, I took Don to lunch. We had a great time reminiscing about MTS. Dawn is one of the nicest people I have ever known.

Thoughts and prayers also go out to her husband John at this time. This is terrible news!’

Tina wrote: “My heartfelt prayers for my sweet sister of ‘My Three Sons’ Dawn Lynn (Dodie) and her husband John. Don is fighting for his life after brain surgery.”

Lynn’s brother, actor and musician Leif Garrett, 60, told the publication: “My sister Dawn never wanted anyone to know about the operation.

“As this has leaked out on social media, I would really appreciate everyone understanding that these have already been difficult times, having recently lost both parents and a cousin.”

Please keep my sister in your thoughts and prayers and respect our family’s privacy. Thank you.’

My Three Sons, starring Fred McMurray as father Steve Douglas, told the story of a widower raising three children with his stepfather and the children’s uncle.

The series won a Golden Globe for Best Television Show in 1962.

Dawn began acting at the age of four when she appeared as a Native American boy in the 1967 B-grade western Cry Blood, Apache at the age of 4.

In 1969, she played Prudence Everett in the ABC pilot of The Nanny and the Professor, but when the television pilot initially did not sell, her contract with ABC was released.

Lynn has also appeared in shows such as Adam-12, Emergency!, Marcus Welby, MD, Barnaby Jones and Gunsmoke.

In 1971, she played the daughter of Gregory Peck’s character in the film Shoot, and also played the title role in a 1973 episode of Manix.

Her last screen acting credit was in the 1978 Wonder Woman episode “My Teen Idol Is Missing.”

Don quit acting in 1977 and was last known to be working in real estate.
