The board of trustees of Long Wharf Theater on Tuesday evening fired the longtime artistic director Gordon Edelstein over accusations of sexual misconduct.

The board of the New Haven theater acted one day after The New York Times published an article detailing the allegations by multiple women, four of whom accused Mr. Edelstein of groping or other forms of unwanted touching. Several former employees also said Mr. Edelstein frequently used sexually explicit language toward and about women in the workplace.

“The board of trustees voted to terminate Gordon Edelstein, effective immediately,” Laura Pappano, the board chairwoman, said in an interview. She said Mr. Edelstein had been barred from the theater’s premises as of Monday.

Ms. Pappano said that board would hire an independent agency to conduct a review of the theater’s procedures for reporting misconduct, and that “implicit in that” is a desire to understand what went wrong during Mr. Edelstein’s tenure. “We want to do better,” she said. “All of this reporting has brought to our attention things that we did not know about, and we feel strongly that going forward we want to know.”
