A prominent Manhattan publisher has been accused of very Harvey Weinstein-like behavior in a new lawsuit by a former employer who says she was punished professionally for reporting his perverted ways a year ago.

The Manhattan Supreme Court suit ​was filed against Knight Landesman, 67, the powerful publisher of Artforum magazine, and ​it also names ​the periodical​ as a defendant​.

Amanda Schmitt, 27, says Landesman, 67, targeted “young and professionally vulnerable” employees — demanding back rubs, grabbing their buttocks and describing graphic sex acts.

In 2012, just two weeks into her job as a saleswoman for the magazine, Schmitt was told by Landesman that she “had a ways to go” to becoming a saleswoman and that her behavior with clients could be seen as “brown-nosing,” according to the suit.

He used that term to pivot toward “overt sexual harassment,” the suit says.

In an email he allegedly told Schmitt, “If I can be so explicit I’d like to take the ‘brown nosing fear’ all the way back to its source. … I for one have felt that when I am making love to a person and they need their a–hole touched or even licked to get off, then I am happy and ready to go there.”

Shortly after that he “invited her to tea, ostensibly to discuss her career, then forcibly grabbed her by the shoulders and tried to kiss her,” Schmitt’s suit says. He called her “prissy” for pushing him away, according to court papers.

He later ran his finger from her lower lip and down past her belly button, asked how often she was masturbating, and texted her an image of a man spanking a woman, the suit says.

Schmitt, who is now 27, claims that a half dozen other young women have reported similar abuse.

“Landesman insisted that they accept his disgusting overtures if they wanted his assistance to thrive in the art world,” she says in the suit.

Much like Weinstein’s reputation as an alleged serial harasser Landesman’s conduct was “widely, albeit privately, commented on in the art world,” according to the filing.

When Schmitt reported the behavior to the magazine’s other publishers last year they allegedly said that “Landesman is not as bad as Harvey Weinstein.”

​​She’s suing for $500,000 claiming she was frozen out of Artforum events and dinners after reporting Landesman, who announced his resignation Wednesday morning after the alleged harassment was made public.

A spokesman for Artforum said, “In the past days, we have met with our staff and they have told us that Knight Landesman engaged in unacceptable behavior and caused a hostile work environment.”

“We will use this opportunity to transform Artforum into a place of transparency, equity, and with zero tolerance for sexual harassment of any kind,” the spokesman added.

​Landesman did not immediately respond to a call for comment.​
