In an emotional tribute to his late father, Zak Williams expressed that he often hears stories about the significant impact his father had on their lives.

At one point, Robin Williams was on top of his game, giving outstanding performance after memorable performance, making people laugh, and spreading pleasure all over the world.

As a result, his death in 2014, at the age of 63, rocked Hollywood and beyond.

Just a few months before his suicide, Williams received a Parkinson’s disease diagnosis.

The autopsy also revealed that he had undetected Lewy body dementia.

The actor’s 73rd birthday was on July 21, and his 41-year-old son, Zak Williams, paid homage on social media.

Zak posted on Twitter: “Dad, on what would be your 73rd birthday, I remember you for all the hope and joy you brought to the world,” he said.

“Not a week goes by without someone telling me about how you helped them get through a difficult moment. I am incredibly grateful to be your kid. “I love you forever.”

In the comments section, fans of Zak’s father proceeded to laud the actor and comedian.

“There was no one remotely like him, either before or after. What a blessing he was. “I’m so sorry for your loss—and ours,” one person remarked.

“Zak, I don’t remember any unpleasant days, but your father made my childhood great. He was a tremendous inspiration, and I still look up to him now. He reminds me that life is enjoyable, and to this day, he is the role model I try to be for my children,” said another thankful admirer.

A third wrote, “Your father was a genuinely great human being who provided pleasure, love, and, most importantly, laughter to millions.” A third wrote.

“Happy birthday, your father. Despite his struggles, he inspired millions of others. He motivated me to be myself. I still wish he was around for this generation. He was an extremely humorous guy. “Thank you for sharing,” another person said.

Zak also remembered his father’s humorous side on August 11, the anniversary of his father’s death, by uploading a photo of Williams at the 1999 Mercedes-Benz Cup celebrity tennis event.

“Dad, on the 9th anniversary of your passing, I’m remembering you for your most excellent fashion choices,” he posted on Twitter.

“These days are always difficult, and I love remembering you for being so very, very YOU. I love you so much!”
