In 1978, Harvey Milk asked Gilbert Baker to create a unifying symbol for the growing gay rights movement, and on June 25 of that year, Baker's Rainbow Flag debuted at San Francisco's Gay Freedom Day Parade. Baker had no idea his creation would become an international emblem of liberation, forever cementing his pivotal role in helping to define the modern LGBTQ movement. Rainbow Warrior is Baker's passionate personal chronicle, from a repressive childhood in 1950s Kansas to a harrowing stint in the US Army, and finally his arrival in San Francisco, where he bloomed as both a visual artist and social justice activist. His fascinating story weaves through the early years of the struggle for LGBTQ rights, when he worked closely with Milk, Cleve Jones, and the Sisters of Perpetual Indulgence. Baker continued his flag-making, street theater and activism through the Reagan years and the AIDS crisis. And in 1994, Baker spearheaded the effort to fabricate a mile-long Rainbow Flag--at the time, the world's longest--to celebrate the twenty-fifth anniversary of the Stonewall uprising in New York City. Gilbert and parade organizers battled with Mayor Rudy Giuliani for the right to carry it up Fifth Avenue, past St. Patrick's Cathedral. Today, the Rainbow Flag has become a worldwide symbol of LGBTQ diversity and inclusiveness, and its colorful hues have illuminated landmarks from the White House to the Eiffel Tower to the Sydney Opera House. Gilbert Baker often called himself the "Gay Betsy Ross," and readers of his colorful, irreverent, and deeply personal memoir will find it difficult to disagree.
