Search “Nina Hartley” and you’ll find dozens of biography pages that all say roughly the same seven things — her age, her height, her net worth — and none of them agree with each other. One site says she’s worth $145,000. Another says $10 million. Some call her husband “Ernest Greene.” Others never explain that this is a stage name at all. Nobody mentions why she quit nursing, or where the name “Nina Hartley” actually came from.
This guide fixes that. Below is a complete, fact-checked look at who Nina Hartley is, how she built a four-decade career, and what’s actually true about her age, education, family, relationships, and net worth.

Who Is Nina Hartley?
Nina Hartley is the professional name of Marie Louise Hartman, an American performer, director, and sex educator who has spent more than 40 years in the adult entertainment industry. What sets her apart from most people in her field isn’t just longevity — it’s the way she’s built a second, parallel career as a registered nurse, published author, and guest lecturer at some of the country’s most respected universities.
She’s often described as a “feminist porn star,” a label she embraced early on. Rather than treat her two worlds — nursing and adult film — as separate, Hartley has spent decades arguing they come from the same place: a belief in giving people honest, judgment-free information about their own bodies.
Early Life and Family Background
Marie Louise Hartman was born on March 11, 1959, in Berkeley, California — a city that, in the late 1950s and ’60s, was becoming one of the most politically active places in America. That environment shaped her family directly.
She was the youngest of four children. Her father, Louis Hartman, was Lutheran; her mother, Blanche Hartman (née Gelders), was Jewish. Both parents had ties to left-wing political activism, and the family later moved toward Buddhism. Her maternal grandfather, Joseph Gelders, was a physics professor at the University of Alabama who became a well-known labor and civil rights organizer in the 1930s — activism serious enough that it got Hartley’s father blacklisted during the McCarthy era. Her extended family tree also includes an aunt, civil rights activist Marge Frantz, and a great-aunt, author Emma Gelders Sterne.
Growing up around that kind of political engagement is part of why Hartley describes herself as a feminist from her teenage years onward — long before she ever stepped in front of a camera.
Education: How a Nursing Student Became an Adult-Film Icon
This is the part most competitor articles get half-right. Yes, Nina Hartley has a nursing degree. But the full story is more interesting than a one-line mention.
Hartley graduated from Berkeley High School in 1977 and enrolled at San Francisco State University, where she earned a Bachelor of Science in Nursing, graduating magna cum laude in 1985. While still a student, she began working as an exotic dancer at San Francisco’s Mitchell Brothers O’Farrell Theatre to help pay for school — and that job became her entry point into adult entertainment.
According to interviews she’s given over the years, she eventually stepped away from bedside nursing not because of the adult industry, but because she found it emotionally difficult to watch patients die. She has, however, stayed connected to healthcare throughout her career, holding an active nursing license for years and frequently drawing on her medical background in her sex-education work.
Even her stage name has a specific origin most bios skip entirely: she has said she chose “Nina” because it was easy for Japanese tourists to pronounce during her dancing days, and “Hartley” as a nod to actress Mariette Hartley, who was well known at the time for a series of TV commercials.
Career: From Dancer to Adult-Film Legend
Breaking Into the Industry
Hartley’s first adult film, Educating Nina (1984), was directed by Juliet Anderson. It was the start of what would become one of the longest careers in the industry’s history — by 2017, she had appeared in more than 1,000 films.
Crossing Into Mainstream Media
Unlike most performers of her era, Hartley successfully crossed over into mainstream Hollywood. Her most recognized mainstream role came in Paul Thomas Anderson’s Boogie Nights (1997), where she played a small but memorable part. In 2008, she took on a very different kind of role in the political satire Who’s Nailin’ Paylin?, portraying Hillary Clinton opposite Lisa Ann’s Sarah Palin.
She’s also appeared in two notable documentaries that rarely get mentioned in competing articles: After Porn Ends (2012), which followed former performers after leaving the industry, and Sticky: A (Self) Love Story (2016), an Amazon-recognized documentary where she discussed sex-positive education and self-acceptance.
Directing and Instructional Work
Hartley moved behind the camera in 1992 with her directorial debut, Nina Hartley’s Book of Love. Two years later, in 1994, she launched the Nina Hartley’s Guide series — a line of instructional videos covering everything from basic intercourse and foreplay to more advanced topics like bondage. The series became one of the best-known educational products in the adult industry and ran for years.
She also authored Nina Hartley’s Guide to Total Sex, a book covering sex toys, non-monogamy, and other relationship topics, which was praised by trade reviewers as frank, well-informed, and sensitively written.
Awards and Recognition
Over her career, Hartley has been inducted into both the AVN Hall of Fame and the XRCO Hall of Fame — two of the industry’s highest honors. Beyond the awards themselves, she’s built a reputation as an educator: she has guest-lectured at Harvard University, Dartmouth College, UC Berkeley, and the University of Wisconsin–La Crosse, discussing sexuality, feminism, and the adult entertainment business in an academic setting most performers never get access to.
Advocacy and Sex Education Work
Hartley’s advocacy work goes beyond her instructional videos. She has been affiliated with the Free Speech Coalition, an organization that lobbies on behalf of adult industry rights, and serves on the team at the Woodhull Freedom Foundation, a nonprofit focused on sexual freedom as a human right. Much of her public speaking centers on destigmatizing sex work, promoting consent education, and encouraging open conversations about sexuality — themes that tie directly back to her nursing background and her family’s activist roots.
Personal Life: Husband, Relationships, and the “Ernest Greene” Mix-Up
Here’s where a lot of competitor articles get confused, and it’s worth clearing up properly.
Nina Hartley has been married twice. Her first marriage was to David Arthur Carr, from 1986 until their divorce in 2003. For part of that marriage, Hartley was openly in a three-way relationship involving her husband and another woman — she has described this period candidly in interviews as part of her long-standing identity as bisexual and non-monogamous.
In 2003, she married her second husband — and this is the detail most bio sites miss. His legal name is Ira Levine, but he’s known professionally in the adult film industry under the pseudonym Ernest Greene, working as a writer and director. They are not two different men, as some articles imply by listing both names separately without explanation — it’s one person using a stage name, the same way “Nina Hartley” is a stage name for Marie Louise Hartman. The couple has described their relationship as openly polyamorous. Hartley does not have any children.
Height, Appearance, and Physical Stats
Nina Hartley stands 5 feet 4 inches tall (approximately 163 cm), with blonde hair and blue eyes — physical traits she’s noted have become part of her recognizable on-camera image over a four-decade career. Weight figures circulating online vary widely and aren’t independently verifiable, so treat any specific number with caution.
Nina Hartley’s Net Worth: What’s the Real Number?
This is the single biggest inconsistency across existing coverage. Depending on which site you check, Hartley’s net worth is reported anywhere from $145,000 to $10 million. Neither extreme is well-supported by sourcing, and no audited or self-reported figure exists publicly — which is normal for someone whose income comes from a mix of film royalties, directing fees, instructional video sales, book royalties, and speaking engagements rather than a single disclosed salary.
Based on the range most consistently cited across multiple entertainment finance trackers, a reasonable estimate places her net worth between $4 million and $6 million, built over 40+ years across acting, directing, authoring, and public speaking. Readers should treat this as an informed estimate, not a confirmed figure.
Social Media
Hartley maintains an active public presence, including an Instagram account (@miss_nina_hartley) and a Twitter/X account (@ninaland), where she shares updates on speaking engagements, advocacy work, and her personal life.

Conclusion
Nina Hartley’s story is bigger than the handful of recycled facts most biography pages repeat. She’s a registered nurse who became one of the most enduring names in adult entertainment, a feminist who has spent decades defending sex work as legitimate labor, and an educator whose instructional work reached far beyond the industry that made her famous — all while lecturing at Ivy League universities and staying married to a partner most people don’t realize is the same person listed under two different names online. At 67, with a career now spanning over four decades, she remains one of the few performers of her generation to have successfully built a life — and a legacy — on her own terms.
