See Rare Photos of Lupita Nyong'o Onstage at Yale

 
Before she nabbed the Best Supporting Actress award for 12 Years A Slave at the 2014 Oscars – and became one of Hollywood's rising style icons in the process – Lupita Nyong'o honed her craft at the Yale School of Drama.

Yale's Chair of the Acting Department Ron Van Lieu, who auditioned Nyong'o, says the Oscar-winner relied on "instinct and an innate sense of truthfulness" when she first started. "She's incapable of lying as an actor, so she had all of that but very little technique."

Mexican-born and Kenyan-raised Nyong'o, 31, was hit by the acting bug after watching Steven Spielberg's 1984 film The Color Purple starring Whoopi Goldberg and Oprah Winfrey.

"I was 9 when I watched The Color Purple," Nyong'o tells PEOPLE. "It was the first time I remember seeing people who look like me onscreen, my textured hair and complexion. It struck me that I might want to do that someday."

She went on to study acting at

Hampshire College and later enrolled in Yale, where she starred in numerous productions that ultimately got her the audition for 12 Years.

Here are rarely seen photos of the Oscar winner on stage during her grad school days.

Van Lieu directed Nyong'o as Sonya in this 2010 production of Chekhov's Uncle Vanya. "The quality of her acting became very clear. She brought a deep understanding of the spirituality by which that character had learned to survive ... somewhat of the same quality she was able to bring to 12 Years A Slave," he says.

"She was a member of an ensemble," Van Lieu says of the 2011 adaptation of the Gertrude Stein poem Doctor Faustus Lights The Lights. "It's a really abstract work, but she's an extraordinarily good team player."

Nyong'o dominated the stage in 2011 as the headstrong Katherine in The Taming of the Shrew says Van Lieu. "It was a no-holds-barred performance," he says. "It was an interpretation of the play in which Katherine ends up poisoning everyone at the end. You always assume she is undone by the end of the play, but she made her a survivor."

CEO Of Bitcoin Exchange Dies In Singapore

SINGAPORE (AP) - The CEO of a virtual currency exchange was found dead in her home in Singapore.
A police spokesman said Thursday that initial investigations indicated there was no suspicion of "foul play," meaning officers do not suspect murder.
The spokesman said 28-year-old Autumn Radtke, an American, was found dead in her home on Feb. 26.
Police have so far classified the death as "unnatural," which can mean an accident, misadventure, or suicide.
Radtke's company, First Meta, said it was "shocked and saddened by the tragic loss."
First Meta allows users of virtual currencies such as bitcoin to trade and cash out the currencies. It is one of several such exchanges.
The future of bitcoin has been under scrutiny since the collapse of the Mt. Gox exchange in Tokyo last month.
Radtke had worked at other tech companies.
Postings on her Facebook page showed her to be a believer in the potential of virtual currencies.
Last month she linked to an article on entrepreneurs suffering depression, commenting above the link: everything has its price.
