Actress Elizabeth Kemp died on Sept. 1 at the age of 65.
Kemp died after a battle with cancer in Venice, California, according to The Hollywood Reporter.
Kemp performed in a number of plays, TV shows and films, starring alongside Christopher Reeve in the 1970s CBS soap opera "Love of Life"and working with Tom Hanks in his first on-screen acting role in the 1980s horror thriller "He Knows You're Alone."
More recently, she appeared as Abel Ferrara's in 2014's "Welcome to New York."
The actress was also an influential teacher at the Actors Studio, coaching the likes of Bradley Cooper and Lady Gaga, who will be acting in Cooper's remake of "A Star Is Born."
Her role as a teacher left a deep impact on her personally and on those around her.
"I think the most exciting thing is when you truly do help," she once explained about her new career path, CNN reports. "And you see them grow and open. 'Cause it isn't about me. It's about helping them grow. That's all I care about. Anything and everything I will do to make that happen, I'll do."
Her students certainly agree.
Kemp helped Cooper in a number of roles, including his Oscar-nominated performance in 2014's "American Sniper."
"I was never able to relax in my life before [meeting] her," Cooper said in a 2011 interview with "Inside the Actors Studio," before choking up and adding the class was "the most sacred experience I've ever had."
"She made it safe," he added. "She made us realize that you have to use all of yourself. She just made it OK, OK to be yourself with all your faults and your fears and insecurities -- they were all brought out to the light and she insisted that you be vulnerable and put it all out there; there was no sort of faking."
On Sept. 2, actress and singer Lady Gaga dedicated her song "The Edge of Glory" to Kemp during her concert at Boston's Fenway Park.
"She was such a strong woman," Gaga said. "She used to ask me all the time to go back to the hardest thing in my heart [to draw on for a performance]. We both understood each other."
"[She had a] real artistic swagger, the kind that you pray for as a young artist ... you dream that one day you become that wise and intelligent about the work," added the singer.
Many on social media mourned the loss of the actress and paid tribute to her life.
"Elizabeth Kemp I celebrate your life and am profoundly grateful to have spent precious time with you," tweeted actor Hugh Jackman.
