When the last lingering Munchkin from “The Wizard of Oz,” Jerry Maren, died in May, at the age of ninety-eight, I took the news harder than I had thought possible. “People come and go so quickly here” is the camp one-liner from the movie, but Munchkinland was one place where people could be relied upon to live forever. A hundred and twenty-four little people were employed in the making of “Oz,” and the survival of a few dozen of them long after the deaths of the movie’s gaudier alumni—Judy Garland, Bert Lahr, Margaret Hamilton—sometimes felt cosmically deliberate, a masterstroke of mythic structure. We have always relied on mortals to attest to the acts of the gods, and the ex-Munchkins cottoned to their role as a sort of ever-dwindling Greek chorus, riding on parade floats and pontificating about the meaning of “Oz” on television. “We finally got recognized,” Maren explained, in 1989. “You know, after everybody else died, they said, ‘Who’s left?’ ”

As the central member of the Lollipop Guild, Maren’s claim to Munchkinhood was the strongest, and he became a familiar screen presence for me. My teen-age summers were usually spent jobless and alone, watching Turner Classic Movies in my basement, as if it were a bunker for laying low until it was 1932 again. The documentary “Memories of Oz” was in heavy rotation then, and it offered a thin soup of secondhand testimonials from John Waters and the spawn of the original stars—until, finally, cathartically, Maren appeared, warbling the Yip Harburg lyrics that were his birthright and gnawing on a cigar as though he were worried he wouldn’t absorb all the nutrients.

I had come to my bunker to pray, and Maren was “a piece of the true cross,” as the original C-3PO, Anthony Daniels, once called himself. His tales of filming “Oz” were shopworn but full of humanizing little details: between takes, the eighteen-year-old Maren played with a small hunk of clay (modelling was his hobby at the time) while M-G-M technicians mopped up the water that was perpetually leaking from the Munchkinland pond onto the Yellow Brick Road. When asked about Judy Garland, he’d say, “I thought she was going to be a toughie, but she wasn’t.”

Journalists who spoke to ex-Munchkins did it strictly from hunger, but, in the rare instances when they went deep, an almost unbearably poignant narrative emerged. Dwarfism was widely misunderstood at the dawn of the twentieth century, and many of the little people of “Oz” had emerged from medieval childhoods: their parents had immersed them in barrels of coconut oil, force-fed them to promote growth, and strapped them onto stretching racks. One peasant family sold their daughters to a travelling dwarf impresario at a hundred and fifty dollars a head. Walter Bodin and Burnet Hershey’s little-people exposé, “It’s a Small World,” from 1934, reflects the attitudes of the era, with vague talk of “our mysterious glands” and a litany of infantilizing stereotypes. “The authors have met many midgets who are constant consultants of Ouija boards, star seers, and crystal gazers,” Bodin and Hershey write. “They lug phonographs and radio sets about, ever prepared for a revel . . . . Many midgets are amazingly vain . . . . They are suspicious, given to small jealousies . . . and are extremely partial to ‘parties’ which last far into the night.”

Maren was spared the most draconian growth treatments of the day, but his memoir, “Short and Sweet,” published in 2006, recounts a childhood of tragic isolation. His immigrant parents spoke mostly Italian, which he couldn’t understand, and his ten older siblings were all average-sized. Until Maren boarded an M-G-M-chartered bus bound for Culver City in November, 1938, he had never seen another little person. “My eyes lit up,” he wrote of that first sighting. “I wondered if they walked like me. Did they have a high-pitched voice like me? Do they eat the same things as me?”

Gay people, trans people, little people: we’re all born in helpless diaspora, and reconstituting the dandelion is the dilemma of our lives. For the hundred and twenty-four little people who descended on the set of Munchkinland, it was a moment of homecoming. When the dwarf Hazel Resmondo walked onto the soundstage, she wept. Several little people met their husbands and wives while making the film, and others formed lasting friendships. “The experience made me feel like maybe I wasn’t so bad after all,” Fern Formica, who played a Sleepyhead, said, in 1991. “Maybe I was as good as anyone else.” According to the activist Billy Barty, the unprecedented congregation of little people on “Oz” led to the formation of the Midgets of America advocacy group; now known as Little People of America, it boasts more than six thousand members.

But that’s not what comes to mind when the subject of Munchkins is broached. The pervasive rumor is that drunken orgies regularly took place at the Culver City Hotel, where most of the little people lived while shooting “Oz.” Judy Garland helped craft this myth herself; in an interview with Jack Paar, in 1967, she said, “They were drunks . . . . They got smashed every night, and they’d pick ’em up in butterfly nets.” No talk-show anecdote has had such a barnacle hold on the American consciousness. In 1981, Garland’s dehumanizing take on the Munchkins was more or less adapted into the cornball Chevy Chase comedy “Under the Rainbow,” and the story has since been perpetuated by media figures ranging from Sally Jessy Raphael (“an absolute orgy went on”) to NPR’s Scott Simon (“there was a Roman-like scene”). The film historian Hugh Fordin called the Munchkins an “unholy assemblage of pimps, hookers, and gamblers . . . the most deformed, unpleasant bunch of adults imaginable.”

It’s almost entirely untrue. Aljean Harmetz, a longtime Hollywood correspondent for the Times, debunked the rumors in her authoritative book “The Making of ‘The Wizard of Oz,’ ” though she admitted that “there were among them a few promiscuous women, a few sexually aggressive men.” The only contemporary evidence of Munchkin misbehavior is a December 30, 1938, memo from the production manager Keith Weeks concerning the potential dismissal of two bad eggs: Charley Kelley, who had assaulted his wife, and another dwarf (either Gus Wayne or Leon Polinsky), who had “tried to knife [an] assistant, Mr. Torelli, in an altercation.” But the legends of widespread Munchkin debauchery were too seedy and captivating to disregard; they came up in every interview that Jerry Maren did. “That’s a lot of hooey,” he told the Times, in 1997.

In 1971, the poet Ted Hughes described the uncanny afterlife of tabloid stories, writing, “For your readers, it’s five interesting minutes, but for us it is permanent dynamite.” Garland’s tossed-off anecdote was a kind of dynamite, and the Munchkins spent the rest of their lives trying to defuse it. After a darker version of Garland’s story surfaced in the press last year, the Australian writer Gary Nunn wrote that he’d “spent the best part of the last fortnight urgently trying to track down” Maren—by then suffering from dementia—for an official statement.

It’s strange that so many journalists dwell on the orgies when a genuine Munchkin scandal has gone virtually unreported for seventy-five years. In the nineteen-seventies, the producer of “Oz,” Mervyn LeRoy, recalled that he wanted to amass a group of “little people who were little and cute and looked perfect.” Consequently, Munchkin headhunters were instructed to weed out achondroplastic dwarfs and dwarfs of color. Nobody involved in the production seems to have questioned the Jim Crow strictures of Munchkinland. It’s as if they all thought, Of course—why on earth would Dorothy dream about black people?
