Hannah Beachler's emotional speech during historic Oscars production design win: 'My best is good enough'

Hannah Beachler on Sunday made history as the first African-American to be nominated for -- and win -- an Academy Award in production design for her work on "Black Panther."

In an emotional speech, Beachler thanked "Black Panther" director Ryan Coogler.

Coogler "not only made me a better designer, a better storyteller, a better person," she said, shaking at times. "I stand here because of this man who offered me a different perspective of life, who offered me a safe space, and gave me air, humanity and brotherhood."

"I am stronger because of Marvel, who gave me the opportunity to do my best, who supported the vision of this film and lifted us up every day," she said.

She went on, "I am stronger because of my family who supported me through the roughest of times. I give the strength to all of those who come next to keep going, to never give up. And when you think it's impossible, just remember ... this piece of advice I got from a very wise woman: I did my best and my best is good enough."

Reese Witherspoon was among those moved by the powerful speech.

After her win, in a backstage interview for "Good Morning America," Beachler told ABC News' Lara Spencer, "I want all the young women of color and girls of color to be able to now stand on my shoulders."

"Because I have stood on so many shoulders of all the women that came before me ... that have fought for me to be here," Beachler said. "That's what this means to me ... now it's my turn to give."

Beachler's "Black Panther" colleague Ruth Carter also made history Sunday night, becoming the first African-American to win the Oscar for best costume design.

Disney is the parent company of ABC and Marvel.
