Sidney Poitier's Death Certificate Unveils Several Diseases — One of Them Also Took His Brother's Life

One of Sidney Poitier's brothers died in 1991 after dealing with one of the diseases that took the Hollywood legend's life early this month.

The renowned actor Sidney Poitier passed away at 94 years old, at his home in Beverly Hills after his 76-year career that saw him become the first Black man to win an Oscar for Best Actor.

According to TMZ, Poitier's death certificate stated he died from a combination of three different conditions, heart failure, Alzheimer's dementia, and prostate cancer.

After his passing, his daughter Syndey Poitier shared a touching tribute on her Instagram account. She wrote about how good of a person he was, his impact on others, and how he dealt with his illness.

The "Lilies of The Field" actor was first diagnosed with prostate cancer in 1993, at 66 years old. At the time, he successfully treated cancer with surgery, which is a standard treatment option for prostate cancer.

Before Poitier was diagnosed, the family went through another tragedy, the passing of his older brother, Cyril Poitier. Cyril passed away on November 13, 1991, from cancer.

He was the oldest of the eight Poitier siblings. Cyril played an essential role in Poitier's life as he took him in when he was 15 years old. Cyril once remarked that he was strict with his younger brother:

"I was very strict with him. He'd always look up to me, listened to my advice."

Unfortunately, Poitier and his family did not only experience the tragic loss of his brother, but the family was again struck with heartbreak as Poitier's daughter Gina passed away in 2018.

Gina was her father and mother, Juanita Hardy's youngest child. Poitier and Hardy welcomed four children, Gina, Beverly, Pamela, and Sherri, together during their marriage from 1950 to 1965.

She passed away at 57. The family did not share her cause of death. However, in her

, they acknowledged that her passing was quick and unexpected and would miss her deeply.

Poitier was most known for his roles in movies such as "Who's Coming to Dinner?" "To Sir, With Love," "In The Heat of The Night," "A Patch Of Blue," and "Lilies of The Field."

Poitier started his career when racial segregation in America was rife. So his contributions and efforts to work in Hollywood made progress and paved the way for his fellow Black actors.
