"I can't swim wearing more stuff than you hang on a clothesline." That was Annette Kellerman's verdict on what women of her day were required to wear into the water. In the early 1900s, a proper woman entered the sea in a heavy wool dress over pantaloons, with sleeves, black stockings, and sometimes slippers -- an outfit that made real swimming nearly impossible, and could pull a struggling swimmer under. Kellerman, the most famous swimmer in the world, thought this was not only absurd but dangerous, and she set out to change it, one scandalous swimsuit at a time.
The fight once landed her in a jail cell. In 1907, on Revere Beach just north of Boston, Kellerman was arrested for public indecency -- her crime a formfitting one-piece that bared her arms and showed the shape of her legs where custom demanded yards of wool. "Me, arrested!" she recalled years later. "We were all terribly shocked, especially my father, for I was his innocent protected little girl. But the judge was quite nice and allowed me to wear the suit if I would wear a full-length cape to the water's edge."
For decades, cities policed women at the beach. They hired "censors" and sent officers out with tape measures to kneel in the sand and check the distance between a woman's knee and the hem of her suit. In 1921, Chicago launched a swimsuit patrol to ticket offenders; Coney Island sent plainclothes officers to hunt for bare legs over a holiday weekend; and when Atlantic City banned one-piece suits and bare legs in 1923, fifty women were ordered off the beach in a single day.
Thousands were fined or arrested across the decade, their names printed in the papers under headlines about a "war on indecency," while the officers posed for photographers. The kind of suit Kellerman championed was, in parts of the United States, against the law.
That she of all people ended up fighting for the freedom to move through water was its own kind of proof of what swimming could do. Annette Kellerman was born in 1886 in Marrickville, a suburb of Sydney, Australia, to two music teachers. As a small child she could not walk without heavy steel braces on her legs; a condition believed to be rickets had left them weak and bent.
Doctors prescribed swimming to strengthen them, and it worked -- slowly, and then completely. She later wrote of the "intense joy" she experienced "when little by little I found that my legs were growing stronger." By her teens the braces were gone, and she was winning championships.
She turned professional in part to help her struggling family, and she made her name through sheer nerve. In 1905, at nineteen, she became one of the first women to attempt to swim the English Channel, greasing herself against the cold and lasting more than ten hours in the water before she was pulled out, three-quarters of the way across. She tried three times and never made it. "I had the endurance," she said, "but not the brute strength." Even so, the record she set on that failed attempt stood for years.
Kellerman conquered nearly everything else. She swam the Thames before enormous crowds, then beat the Austrian Baroness Walpurga von Isacescu -- the first woman ever to attempt the Channel herself -- in a twenty-two-mile challenge race down the Danube, and raced against men down the Seine before a Paris crowd said to number in the hundreds of thousands.
Then she took her talent onto the stage, filling theaters as "the Australian Mermaid," diving and performing underwater ballet in the glass tanks that were the marvel of the vaudeville era -- and, in the process, helping to invent the sport we now call synchronized swimming.
Her celebrity reached a strange peak in 1910, when Dr. Dudley Sargent, the director of Harvard's Hemenway Gymnasium, measured thousands of women and pronounced Kellerman "the perfect woman," her proportions a near match for the Venus de Milo. She wore the title lightly. She was perfect, she liked to say, only "from the neck down."
She went on to Hollywood, starring in lavish aquatic spectacles and performing her own dangerous stunts -- diving some ninety feet into the sea, and sixty feet into a pool stocked with crocodiles, once bound hand and foot. In the 1916 epic "A Daughter of the Gods," the first film ever to cost a million dollars, she became the first major actress to appear n**e on screen.
But the achievement she claimed as her proudest was the plainest one. The suit she had been mocked and arrested for -- the one that let a woman actually swim -- caught on, first as a scandal and then as a fashion, sold the world over as "the Annette Kellerman." Long after her diving and her films were forgotten, women were still swimming in what she had made possible.
She had done it, in the end, for the same reason she had first been put in the water as a girl who could not walk. Of all her records and films and headlines, freeing women from the wool and the stockings and the slippers was the achievement she claimed as her greatest -- not the diving or the fame, but the plain, hard-won right of a woman to move freely through the water. Swimming, she once wrote, was "not only a splendid sport for women but... the sport for women."
