At the age of 14, Carr met David Kammerer (b. 1911), a man who would have a profound influence on the course of his life. Kammerer was a teacher of English and a physical education instructor at Washington University in St. Louis. Kammerer was a childhood friend of William S. Burroughs, another scion of St. Louis wealth who knew the Carr family. Burroughs and Kammerer had gone to primary school together, and as young men, they traveled together and explored Paris’s night life: Burroughs said Kammerer “was always very funny, the veritable life of the party, and completely without any middle-class morality.”
Kammerer met Carr when he was leading a youth group of which Carr was a member, and quickly became infatuated with the teenager.
Over the next five years, Kammerer pursued Carr, showing up wherever the young man was enrolled at school. Carr would later insist, as would his friends and family, that Kammerer had been hounding Carr sexually with a predatory persistence that would today be considered stalking. Whether Kammerer’s attentions were frightening or flattering to the younger man (or both) is now a matter of some debate among those who chronicle the history of the Beat Generation. What is not in dispute is that Carr moved quickly from school to school: from the Phillips Academy in Andover, Massachusetts to Bowdoin College in Brunswick, Maine to the University of Chicago, and that Kammerer followed him to each one. The two of them socialized on occasion. Carr always insisted, and Burroughs believed, that he never had sex with Kammerer; Jack Kerouac biographer Dennis McNally wrote that Kammerer "was a Doppelgänger whose sexual desires Lucien would not gratify; their connection was an intertwined mass of frustration that hinted ominously of trouble."
Carr’s University of Chicago career ended quickly and badly, with an episode that concluded with the young man putting his head into a gas oven. He explained away this act as a “work of art,”[7] but the apparent suicide attempt, which Carr’s family believed was catalyzed by Kammerer, led to a two-week stay in the psychiatric ward at Cook County hospital. Carr’s mother, who had by this time moved to New York City, brought her son there and enrolled him at Columbia University, close to her own home.
If Marion Carr was seeking to protect her son from David Kammerer, she did not succeed. Kammerer soon quit his job and followed Carr to New York, moving into an apartment on Morton Street in the West Village.
It was at Columbia University that Carr befriended Allen Ginsberg. Soon after, a young woman Carr had befriended, Edie Parker, introduced Carr to her boyfriend, Jack Kerouac. Carr, in turn, introduced Ginsberg and Kerouac to one another – and both of them to his older friend with more first-hand experience at decadence: William Burroughs. The core of the New York Beat scene had formed, with Carr at the center. As Ginsberg put it, “Lou was the glue.”
Carr, Kerouac, Ginsberg and Burroughs explored New York’s grimier underbelly together.
For ten months, Kammerer remained a fringe member of this simmering crowd, still utterly infatuated with Carr, who sometimes avoided him and on other occasions indulged Kammerer’s attentions. On one occasion he may even have brought Kammerer to a session of Trilling’s class. Accounts of this period report that Kammerer’s presence and lovelorn devotion to Carr made many of the other Beats uncomfortable. On one occasion, Burroughs found Kammerer trying to hang Kerouac's cat. Kammerer’s psyche was evidently decaying; he was barely scraping by, helping a janitor clean his building on Morton Street in exchange for rent. In July 1944, Carr and Kerouac began talking about shipping out of New York on a Merchant Marine vessel, a scheme which drove Kammerer frantic with anxiety at the possibility of losing Carr. In early August, Kammerer crawled into Carr’s room via the fire escape and watched him sleep for half an hour; he was caught by a guard as he crawled back out again.
On August 13, 1944, Carr and Kerouac attempted, and failed, to ship out of New York to France on a merchant ship. Kicked off the ship by the first mate at the last minute, the two men drank together at the Beats’ regular bar, the West End. Kerouac left first, and bumped into Kammerer, who asked where Carr was. Kerouac told him. Kammerer caught up with Carr at the West End, and the two men went for a walk, ending up in Riverside Park on Manhattan's Upper West Side.
According to Carr's version of the night, he and Kammerer were resting near West 115th Street when Kammerer made yet another sexual advance. When Carr rejected it, he said, Kammerer assaulted him physically, and being larger, gained the upper hand. In desperation and panic, Carr said, he stabbed the older man, using a Boy Scout knife from his St. Louis childhood. Carr then tied his assailant's hands and feet, wrapped Kammerer's belt around his arms, weighted the body with rocks, and dumped it in the nearby Hudson River.
Carr was charged with second-degree murder. The story was closely followed in the press, involving as it did a well-liked, gifted student from a prominent family, New York's premier university, and the scandalous whiff of homosexuality.[18] The newspaper coverage embraced Carr's story of an obsessed homosexual preying on an appealing heterosexual younger man, who finally lashed out in self-defense. The Daily News called the killing an "honor slaying". If there were subtler shadings to the tale of Carr’s five-year saga with Kammerer, the newspapers ignored them. Carr pled guilty to first-degree manslaughter, and his mother testified at a sentencing hearing about Kammerer's predatory habits. Carr was sentenced to a term of one-to-twenty years in prison; he served two years in the Elmira Correctional Facility in Upstate New York and was released.
