Tutorial conferences are normally staid affairs, however the 1973 Worldwide Symposium on Gender Id, held in Dubrovnik, Yugoslavia, was an exception. All the things was peaceable till a psychologist named John Cash stood and yelled, “Mickey Diamond, I hate your guts!”

Milton Diamond, a sexologist who had passed by Mickey since childhood, was sitting on the opposite aspect of the room. Dr. Cash and Dr. Diamond have been bitter rivals: Dr. Cash, a nationally acknowledged researcher at Johns Hopkins College, had lengthy argued that sexual and gender id are impartial at delivery and formed primarily by an toddler’s environment.

Dr. Diamond, who was simply starting his profession on the College of Hawaii, strongly disagreed, and had mentioned so repeatedly — together with in a extensively learn 1965 critique of Dr. Cash’s work. He took specific concern with Dr. Cash’s advice that intersex infants have surgical procedure to “right” their genitals.

Dr. Cash rushed over to Dr. Diamond, getting in his face, furiously insisting he was proper.

Dr. Diamond solely replied, “The information shouldn’t be there.”

At one level, eyewitnesses reported, Dr. Cash slugged Dr. Diamond, although Dr. Diamond later mentioned he didn’t keep in mind it.

The incident, reported by the journalist John Colapinto in Rolling Stone journal and in a subsequent e book, “As Nature Made Him: The Boy Who Was Raised as a Girl” (2000), was particularly heated due to a latest announcement by Dr. Cash.

He had been working with a baby who in 1965, after his penis was irreparably broken throughout a circumcision, had undergone additional surgical procedure to take away his male genitalia. The kid was then raised as a woman, taking up all the traditional bodily and emotional traits of a feminine adolescent — fortunately, Dr. Cash mentioned.

Although the kid was not born intersex, Dr. Cash claimed that the case proved that gender and sexual id have been malleable and that intersex kids ought to certainly obtain surgical procedure.

Dr. Cash and an affiliate, Anke A. Ehrhardt, now a researcher within the area, offered their findings in a 1972 e book, “Man and Girl, Boy and Lady.” The journalist James Lincoln Collier, writing in The New York Times, known as it “a very powerful quantity within the social sciences to look because the Kinsey reviews.”

However Dr. Diamond remained unconvinced, and mentioned so, a place that fired up Dr. Cash in Dubrovnik. The case examine was inconclusive, he mentioned, including that the kid, who was about 7 when the e book was printed, had not even reached puberty.

It was not till the early 1990s that Dr. Diamond managed to trace down the kid and the psychiatrist who had handled them, H. Keith Sigmundson.

What he discovered demolished all of Dr. Cash’s claims.

The kid, born Bruce Reimer however then raised as Brenda, had rebelled in opposition to the enforced upbringing, tearing off clothes and threatening suicide. At 14, the kid’s dad and mom agreed to cease hormone therapy and permit him to reside as a boy — now beneath a special identify, David.

Worse, Dr. Diamond mentioned he had proof that Dr. Cash, who had met yearly with David and his twin brother, had abused the kids, forcing them to simulate sexual exercise and yelling at them once they refused. Dr. Cash, who died in 2006, denied the accusations.

Dr. Diamond’s findings, which he and Dr. Sigmundson published in 1997, rewrote not simply Dr. Cash’s case examine, but additionally how the medical neighborhood approached intersex infants typically.

Beneath Dr. Cash’s affect, commonplace follow had lengthy been for docs to decide on a intercourse for a child with ambiguous genitalia. Dr. Diamond argued for the other: Id couldn’t be pressured, intersex individuals deserved a spot on the spectrum of human sexuality, and the choice to make adjustments to their physique needs to be left to the person.

Dr. Diamond stayed in contact with David, who ultimately married and adopted his spouse’s kids. He died by suicide in 2004.

Immediately, whereas many docs comply with Dr. Diamond’s suggestions, different docs and lots of dad and mom nonetheless go for toddler surgical procedure, in response to Bo Laurent, the founder and former government director of the Intersex Society of North America.

“Possibly we actually should suppose,” Dr. Diamond advised the BBC in 1980, “that we don’t come to this world impartial; that we come to this world with a point of maleness and femaleness which is able to transcend regardless of the society needs to place into it.”

Dr. Diamond died on March 20 at his dwelling in Honolulu. He was 90. His spouse, Constance Brinton-Diamond, confirmed the loss of life.

Milton Diamond was born on March 6, 1934, within the Bronx to Aaron and Jennie (Arber) Diamond, Jewish immigrants from Ukraine. They owned grocery shops within the borough, and the household moved continuously. He spent part of his childhood in an Irish neighborhood, the place a few of the kids, having by no means met a Milton earlier than, gave him a reputation extra acquainted to them, Mickey. It caught.

In 1955, Milton grew to become the primary scholar on the Metropolis School of New York to obtain a level in biophysics. After three years within the U.S. Military, he attended the College of Kansas and in 1962 earned a doctorate in anatomy and psychology, writing a dissertation on the consequences of testosterone in utero.

Alongside along with his spouse, he’s survived by 4 kids from his first marriage, Hinda, Irene, Sara and Leah Diamond; three stepchildren, Maia James Tidwell, Kristina Brinton and Andrew Brinton; and 14 grandchildren.

Dr. Diamond taught for a number of years on the College of Louisville, then moved to the College of Hawaii in 1967 to hitch the founding college of its new medical college. He took emeritus standing in 2009.

After publishing his 1997 paper on Dr. Cash’s work, Dr. Diamond spent a number of years growing tips for the care of intersex people. He additionally pushed in opposition to the concept being intersex was a dysfunction and argued for its acceptance as a traditional a part of human sexuality.

Nature loves selection, he appreciated to say.
