Mr. Genocchio is not as well known as Mr. Weinstein and the complaints against him typically involve misconduct that is described as more verbal than physical. But in the tight-knit and clubby art world, Mr. Genocchio’s contacts give him outsize power in the business. The Armory Show had connected him with art professionals from all over the world. The casual forms of sexual harassment that he was accused of rarely make headlines but can be insidious because of their pervasiveness, and often goes unchecked.

Another complaint against Mr. Genocchio is laid out in an April 17 memo to Michelle Anastassatos, vice president for human resources at Vornado Realty Trust, which owns the Armory Show. In the memo, obtained by The Times, Deborah Harris, the Armory Show’s managing director, reports being “berated and humiliated” by Mr. Genocchio after chastising him for “frisky behavior” that included, she said, making “lewd comments about the bodies and dress” of staff members. (Ms. Harris declined to be interviewed.)

Amanda Coulson, the artistic director of the Volta art fair, an affiliate of the Armory Show, confirmed that one of her female employees asked to work elsewhere because of Mr. Genocchio’s behavior. “She did not want to work in the office because she felt the environment was hostile,” Ms. Coulson recalled. “So I immediately moved her out and got her another office.”

Several people who worked at the Armory described being present when Mr. Genocchio said he couldn’t have an employee in her 50s accompany him to a sponsorship event at a fashion house because he needed instead to bring “some arm candy.”

Vornado in May acknowledged in a letter to Ms. Harris that Mr. Genocchio had “referred to another female employee as arm candy and previously referred to others as sweetie.”

“However,” the letter continued, “multiple employees indicated that as soon as they told him that his comments were objectionable, he stopped making them, he was apologetic, and that no further comments have been made.” (Vornado, in the same letter, informed Ms. Harris that her job was being eliminated and suggested that “a skeptic might even think that the timing of your complaint to human resources was a strategic attempt by you to try to prevent the termination from occurring.”)
