“Injustice anywhere is a threat to justice everywhere,” Martin Luther King, Jr. wrote in his indispensable 1963 letter from Birmingham City Jail. “We are caught in an inescapable network of mutuality.” One rainy January Sunday fifteen years later, long before Edie Windsor catalyzed the triumph of marriage equality, Harvey Milk (May 22, 1930–November 27, 1978) was sworn into office on the steps of San Francisco’s City Hall and became the first openly gay elected city official in America. His assassination eleven months later devastated millions and rendered him modernity’s great secular martyr for love. His tenure, however tragically brief, forever changed the landscape of civil rights.

In The Harvey Milk Story (public library) — a wonderful addition to the best LGBT children’s books — writer Kari Krakow and artist David Gardner tell the heartening and heartbreaking story of how a little boy with big ears grew up to hear the cry for social justice and how he answered it with a groundbreaking clarion call for equality in the kingdom of love.

Harvey was Born the second child of a middle-class Jewish family in upstate New York. He was a boy at once brimming with joy, frequently entertaining the family by conducting an invisible orchestra in the living room, and full of deep sensitivity to the suffering of others.

He was deeply moved when his mother, Minnie, told him the story of the Warsaw Ghetto Jews who courageously defended themselves even as the Nazis outnumbered them — a story that imprinted him with a profound empathy for the oppressed even before he had a clear sense that he would grow up to be one of them.

Although Harvey was athletic and popular in school, he anguished under the burden of a deep wistfulness — by the time he was fourteen, he knew he was gay, but like many queer people of his time, he kept this centerpiece of identity a closely guarded secret for a great many years to come.

He came of age, after all, in an era when queer couples celebrated their love only in private and when geniuses as vital to humanity as computing pioneer Alan Turing were driven to suicide after being criminally prosecuted by the government for being gay.

After graduating from college, Harvey joined the Navy, becoming an expert deep-sea diver and ascending through the ranks until he came to head a submarine rescue vessel.

When he went to his bother Robert’s wedding, he looked so handsome in his navy uniform that his family and friends all wondered when he would settle down and get married to the “right girl.”

But instead, like the hero of the heartwarming King & King fairy tale, Harvey fell in love and settled down with the right boy, a young man named Joe.

They moved together to a little town in New York, where Harvey became a high school math and science teacher. But after six years, Harvey and Joe separated — as Krakow points out, the pressure to hide their relationship in fear of losing their jobs put an undue strain on their love. Weary of hiding his identity, Harvey moved to San Francisco’s gay-friendly Castro neighborhood — where queer couples walked down the street holding hands like any other couple would in any other city — and he fell in love again.

Together with Scott, his new partner, Harvey opened a small store called Castro Camera, which soon turned into a community center as Harvey became a one-man Craigslist, counseling neighbors on everything from finding apartments to applying for jobs.

The more Harvey listened to the people, the more he sensed that they needed a leader — not only an informal one, but one who fought on their behalf in the eyes of the law, standing up to the police who harassed them constantly and fighting against the daily indignities of discrimination, from which the political system failed to protect them. Harvey saw only one course of action — to apply for office. His customers and the community embraced his campaign and volunteered their time.

Eleven-year-old Medora Payne came every day after school to lick envelopes and hand out brochures for Harvey. She organized a fundraiser at her school, earning $39.28 for his campaign.

Bigots believed that it wasn’t right or even possible for an openly gay candidate to be elected. Indeed, Harvey lost three consecutive election cycles between 1973 and 1976, but didn’t lose faith. He remained emboldened by the unflinching conviction that the rights of minorities — not only the LGBT community, but also African Americans, Asian Americans, senior citizens, and the disabled — weren’t adequately represented in and protected by the government. His people loved him for the dedication.

At last, in 1977, he was elected to the city’s Board of Supervisors and sworn into office the following January as Supervisor Milk. He immediately set out to champion greater quality of life for the people of the city — a kind of Robert Moses without the evil genius, bolstering the city’s parks, schools, and police protection. Eventually, he introduced a pioneering gay bill of rights. After ten of the city’s eleven supervisors voted for it, Mayor George Moscone signed it into law, proclaiming with gusto as Milk stood by his side:

I don’t do this enough, taking swift and unambiguous action on a substantial move for civil rights.

It was a historic moment, marked by a moving speech Milk made in front of City Hall, calling for a gay rights march in Washington.

But as the city celebrated, one man sat consumed with hateful bigotry and personal jealousy — Dan White, the only Supervisor who hadn’t voted for Milk’s bill and who had resigned from office in a petty act of protest, only to ask for his job back ten days later. Sensing his ill will, Mayor Moscone had refused to hire him back.

On a gloomy November morning, White crept into City Hall through a basement window, with a loaded gun. He barged into Moscone’s office and shot the mayor, promptly reloading his gun and heading down the hall to Harvey Milk’s office. Five shots echoed through the marble building.

Harvey Milk was dead.

People everywhere were stunned by the news of the double assassination. They left their homes, jobs and schools to mourn the loss of these two great leaders. Crowds began forming in front of City Hall. By nightfall thousands filled the mile-long street and ran from the Castro to City Hall. They stood in silence, carrying candles. That night the people of San Francisco wept.

Harvey Milk was gone, but his legacy only gained momentum in the fight for civil rights. The following October, a hundred thousand people brought his dream to life and took to the streets of Washington in the capital’s first-ever Gay Pride March, many carrying portraits of the slain San Francisco hero.

Thirty-four years later, one brave woman picked up where he left off and made possible a dream even Milk didn’t dare to dream — one which the president himself proclaimed “a victory for American democracy,” the triumphant road to which Milk had paved.
