One month after the unexpected death of actor Matthew Perry on October 28, Keith Morrison, who is Matthew Perry's stepfather, made a poignant appeal to the actor's family.

"This is not the sort of thing I commonly do, this pitch," the journalist wrote Monday on X, previously known as Twitter, in his first post since Perry's death. "But this year is different. And tomorrow is Giving Tuesday. Do what you can; he would have been grateful."

Those close to Perry also talked about the legacy they want to "honor" after the actor's death.

"It is important to us, as a family, to honor Matthew’s legacy," Perry’s family told Fox News Digital in a statement. "The potential that the Matthew Perry Foundation has to help those suffering from this disease is something we are proud to bring to the world."

In an Instagram story post, the deceased actor's former co-star from "Friends," Jennifer Aniston, also urged supporters to make contributions to The Matthew Perry Foundation.

It was a post from the foundation's Instagram account that she put on her story. The post included a photo of Perry and the quote: "Addiction is far too powerful for anyone to defeat alone. But together, one day at a time, we can beat it down."

"For #GivingTuesday please join me and Matty's family in supporting his foundation - which is working to help those suffering with addiction," she captioned the post, adding "he would have been grateful for the love."

The organization was established in Perry's name on November 3 to assist others battling with addiction, just like the actor did for much of his life.

"The Matthew Perry Foundation is the realization of Matthew's enduring commitment to helping others struggling with the disease of addiction," the mission statement said.

"It will honor his legacy and be guided by his own words and experiences and driven by his passion for making a difference in as many lives as possible."

Perry reportedly drowned at his California residence on October 28, according to law enforcement sources. At the time, he was 54.

The cause of death was classified as "deferred," pending toxicology results, by the County of Los Angeles Department of Medical Examiner, after his autopsy was concluded on October 29.

On November 3, Perry's family and friends convened to honor the late actor. Page Six reports that his family members were spotted at Forest Lawn Memorial Park in Hollywood Hills, which is close to The Warner Bros. property in Burbank, California, where "Friends" was filmed.

Numerous Hollywood celebrities are interred at Forest Lawn, including Bob Barker, Andy Gibb, Forest Lawn, Debbie Reynolds, Carrie Fisher, Paul Walker, and Andy Gibb.
