Splay-legged in the chair, my mother tried to smile. She didn’t want a boy. She had one already. In fact, she was so certain I was going to be a girl that she’d picked out only one name for me: Calliope. But when my grandmother shouted in Greek, “A boy!” the cry went around the room, and out into the hall, and across the hall into the living room where the men were arguing politics. And my mother, hearing it repeated so many times, began to believe it might be true.

As soon as the cry reached my father, however, he marched into the kitchen to tell his mother that, this time at least, her spoon was wrong. “And how you know so much?” Desdemona asked him. To which he replied what many Americans of his generation would have:

“It’s science, Ma.”

Ever since they had decided to have another child—the diner was doing well and Chapter Eleven was long out of diapers—Milton and Tessie had been in agreement that they wanted a daughter. Chapter Eleven had just turned five years old. He’d recently found a dead bird in the yard, bringing it into the house to show his mother. He liked shooting things, hammering things, smashing things, and wrestling with his father. In such a masculine household, Tessie had begun to feel like the odd woman out and saw herself in ten years’ time imprisoned in a world of hubcaps and hernias. My mother pictured a daughter as a counterinsurgent: a fellow lover of lapdogs, a seconder of proposals to attend the Ice Capades. In the spring of 1959, when discussions of my fertilization got under way, my mother couldn’t foresee that women would soon be burning their brassieres by the thousand. Hers were padded, stiff, fire-retardant. As much as Tessie loved her son, she knew there were certain things she’d be able to share only with a daughter.

On his morning drive to work, my father had been seeing visions of an irresistibly sweet, dark-eyed little girl. She sat on the seat beside him—mostly during stoplights—directing questions at his patient, all-knowing ear. “What do you call that thing, Daddy?” “That? That’s the Cadillac seal.” “What’s the Cadillac seal?” “Well, a long time ago, there was a French explorer named Cadillac, and he was the one who discovered Detroit. And that seal was his family seal, from France.” “What’s France?” “France is a country in Europe.” “What’s Europe?” “It’s a continent, which is like a great big piece of land, way, way bigger than a country. But Cadillacs don’t come from Europe anymore, kukla. They come from right here in the good old U.S.A.” The light turned green and he drove on. But my prototype lingered. She was there at the next light and the next. So pleasant was her company that my father, a man loaded with initiative, decided to see what he could do to turn his vision into reality.

Thus: for some time now, in the living room where the men discussed politics, they had also been discussing the velocity of sperm. Peter Tatakis, “Uncle Pete,” as we called him, was a leading member of the debating society that formed every week on our black love seats. A lifelong bachelor, he had no family in America and so had become attached to ours. Every Sunday he arrived in his wine-dark Buick, a tall, prune-faced, sad-seeming man with an incongruously vital head of wavy hair. He was not interested in children. A proponent of the Great Books series—which he had read twice—Uncle Pete was engaged with serious thought and Italian opera. He had a passion, in history, for Edward Gibbon, and, in literature, for the journals of Madame de Staël. He liked to quote that witty lady’s opinion on the German language, which held that German wasn’t good for conversation because you had to wait to the end of the sentence for the verb, and so couldn’t interrupt. Uncle Pete had wanted to become a doctor, but the “catastrophe” had ended that dream. In the United States, he’d put himself through two years of chiropractic school, and now ran a small office in Birmingham with a human skeleton he was still paying for in installments. In those days, chiropractors had a somewhat dubious reputation. People didn’t come to Uncle Pete to free up their kundalini. He cracked necks, straightened spines, and made custom arch supports out of foam rubber. Still, he was the closest thing to a doctor we had in the house on those Sunday afternoons. As a young man he’d had half his stomach surgically removed, and now after dinner always drank a Pepsi-Cola to help digest his meal. The soft drink had been named for the digestive enzyme pepsin, he sagely told us, and so was suited to the task.

It was this kind of knowledge that led my father to trust what Uncle Pete said when it came to the reproductive timetable. His head on a throw pillow, his shoes off, Madama Butterfly softly playing on my parents’ stereo, Uncle Pete explained that, under the microscope, sperm carrying male chromosomes had been observed to swim faster than those carrying female chromosomes. This assertion generated immediate merriment among the restaurant owners and fur finishers assembled in our living room. My father, however, adopted the pose of his favorite piece of sculpture, The Thinker, a miniature of which sat across the room on the telephone table. Though the topic had been brought up in the open-forum atmosphere of those postprandial Sundays, it was clear that, notwithstanding the impersonal tone of the discussion, the sperm they were talking about was my father’s. Uncle Pete made it clear: to have a girl baby, a couple should “have sexual congress twenty-four hours prior to ovulation.” That way, the swift male sperm would rush in and die off. The female sperm, sluggish but more reliable, would arrive just as the egg dropped.

My father had trouble persuading my mother to go along with the scheme. Tessie Zizmo had been a virgin when she married Milton Stephanides at the age of twenty-two. Their engagement, which coincided with the Second World War, had been a chaste affair. My mother was proud of the way she’d managed to simultaneously kindle and snuff my father’s flame, keeping him at a low burn for the duration of a global cataclysm. This hadn’t been all that difficult, however, since she was in Detroit and Milton was in Annapolis at the U.S. Naval Academy. For more than a year Tessie lit candles at the Greek church for her fiancé, while Milton gazed at her photographs pinned over his bunk. He liked to pose Tessie in the manner of the movie magazines, standing sideways, one high heel raised on a step, an expanse of black stocking visible. My mother looks surprisingly pliable in those old snapshots, as though she liked nothing better than to have her man in uniform arrange her against the porches and lampposts of their humble neighborhood.

She didn’t surrender until after Japan had. Then, from their wedding night onward (according to what my brother told my covered ears), my parents made love regularly and enjoyably. When it came to having children, however, my mother had her own ideas. It was her belief that an embryo could sense the amount of love with which it had been created. For this reason, my father’s suggestion didn’t sit well with her.

“What do you think this is, Milt, the Olympics?”

“We were just speaking theoretically,” said my father.

“What does Uncle Pete know about having babies?”

“He read this particular article in Scientific American,” Milton said. And to bolster his case: “He’s a subscriber.”

“Listen, if my back went out, I’d go to Uncle Pete. If I had flat feet like you do, I’d go. But that’s it.”

“This has all been verified. Under the microscope. The male sperms are faster.”

“I bet they’re stupider, too.”

“Go on. Malign the male sperms all you want. Feel free. We don’t want a male sperm. What we want is a good old, slow, reliable female sperm.”

“Even if it’s true, it’s still ridiculous. I can’t just do it like clockwork, Milt.”
