Among the reactions to the death of
Lisa Jakub, a former child actor who starred alongside Williams in the 1993 classic "Mrs. Doubtfire" as Lydia Hillard, said in a note published online that his death was "incomprehensible" and that he had taught her to "stand up for the things that matter."
In the note she posted on her blog, she thanked Williams for sticking up for her when she was kicked out of high school during the filming of the family comedy.
"Robin stood up for me," she wrote. "He was in my corner. I was only 14, but I had already seen that I was in an industry that was full of back-stabbing. And it was entirely clear that Robin had my back."
The film, which was set in San Francisco, starred Williams as a father who, struggling to keep his family together, poses as a nanny in an attempt to win them back.
Jakub recalled explaining to Williams that she had been kicked out of school after he noticed she was upset on the movie set.

Jakub said she hadn't talked to Williams for quite some time but thought she would one day have a chance to thank him for the letter, which "changed her life."
"It taught me that you stand up for the things that matter," she wrote. "And even if your attempts fail, you tried. You told the truth. You took care of your friends. You fought back."
On Thursday, his wife, Susan Schneider, said in a statement Williams' sobriety was intact as "he struggled with his own battles of depression, anxiety as well as early stages of Parkinson's disease, which he was not yet ready to share publicly."
Depression, Jakub said, was something she also struggled with.
"It's real and it's not shameful and there is help available," she said.
