Areport by The New York Times on Thursday brings to light a potentially instance of mass sexual assault by a doctor named Reginald Archibald during his years of practice in New York.

Archibald, an endocrinologist, died in 2007. But his son, Larry, said to The New York Times, “This doesn’t make sense to me.”

Here’s what you need to know.

Over 17 People (a Majority of Them Being Men) Confirmed to the NYT That They Were Abused by Archibald

Breaking News: For 3 decades, hundreds of children went to a doctor because they were not growing. Now he is accused of sexually abusing many of them. https://t.co/uPDT0Gcl98 — The New York Times (@nytimes) October 18, 2018

The NYT report reveals that over 17 individuals have said they were abused by Archibald, and that a majority of these individuals are men. Most of these victims only learned about other victims when the hospital that Archibald worked at, The Rockefeller University Hospital, posted a statement saying it had credible evidence of “inappropriate behavior”.

What’s more, the hospital had credible allegations against Archibald as early as 2004.

The children reported went to Archibald because they weren’t growing at a normal pace. This was Archibald’s specialty: he studied and treated children who were unusually small for their age. More specifically, he was known as a growth specialist, and he often administered growth hormones like testosterone for children, as a hypothesized means to help children achieve normal height.

According to the NYT report, all of the men who shared their experiences with Archibald recalled similar events: Archibald would tell them to disrobe, then he would usually masturbate them or masturbate to them, occasionally to completion.

He also occasionally took pictures of them with a Polaroid camera, and even measured their penises when they were both flaccid and erect. One victim said to the Times, “You are robbed of knowing what’s real and what’s not real. That’s the real cost of this thing.”

Rockefeller Hospital Released a Statement Regarding Archibald’s Behavior on October 5

On October 5, Rockefeller Hospital released a public statement regarding its former doctor. The statement read in part,

“We have come to learn that Dr. Reginald Archibald, who retired from the Rockefeller University Hospital in 1982, engaged in certain inappropriate conduct during patient examinations. The Hospital and University deeply regret pain and suffering caused to any of Dr. Archibald’s former patients.

The statement further relayed a full investigative report that the hospital carried out in 2004, which led to a conclusion that the “allegations were credible” and a determination that “it was likely that some of Dr. Archibald’s behavior toward this patient was inappropriate.”
