Florence Tullis

Florence "Rusty" Tullis (née Steinberg; May 29, 1936 – November 11, 2006), also known as Rusty Dennis,Rusty Mason and Rusty Dennis Mason was an American woman known for being the mother of Rocky Dennis, who was diagnosed with craniodiaphyseal dysplasia. Their story was depicted in the 1985 film, Mask, in which Tullis was portrayed by Cher.

Tullis was born in Brooklyn. Her father was a truck driver. She had two sisters, Dorothy and Bonnie. Tullis was Jewish.

When she was 13, Tullis got kicked out of junior high school for truancy. At age 14, she began smoking marijuana and riding with bikers. At age 15, she dropped out of school and worked as a "hootchy kootchy" dancer at Coney Island.

When she was 17, Tullis married her first husband, truck driver Tommy Mason; two years later, their son, Joshua, was born. The marriage was a bad one, and shortly after the birth of Joshua, Tullis moved back in with her parents on Coney Island. There, she worked as an exhibit hawker. In 1959, she married her second husband, Roy Dennis, a painting contractor and a house painter. That same year, they moved to Covina, California. Their son, Roy L. "Rocky" Dennis was born on December 4, 1961.

Although Rocky appeared healthy, an X-ray technician noticed irregularities in the boy's skull when he was about 2 years old. A battery of tests conducted at UCLA Medical Center confirmed that Rocky had an extremely rare disease, craniodiaphyseal dysplasia, in which abnormal calcium deposits in Rocky's skull would distort his face and make it grow to twice its normal size. Furthermore, doctors told Tullis that her son would experience failing eyesight and hearing and increasingly severe headaches and that the intense pressure would destroy his brain before he turned 7. During the years they lived in Covina and Glendora, California, Tullis insisted that her son lead as normal a life as possible. She ignored doctors who said her son's poor eyesight would prevent him from learning to read, and she disregarded teachers who tried to discourage her from placing him in a public school.
