The First Amendment lost a champion with the April 11 death of the director of ALA's Office for Intellectual Freedom, who fought censorship for 40 years with courage, intelligence, and wit. A look back at the career of a library legend.

In her a genetic disposition to the appeal of tikkun olam was evident, in the course of a life devoted to deploying the law in behalf of progressive causes of special concern to the Jewish people.

My mother's inspiration and perseverance resulted in the development of a light-weight wheelchair, multi-directional conveyances which can climb stairs, remote control 'space garments' to move limbs, sensory devices to help the blind, amongst many other breakthroughs and my mother united the worlds of science, technology and medicine in the first-ever collaboration!

... Mostly I admire her for being a genuinely funny, talented woman, who never gave up on her greatest ambitions. In an industry where youth and beauty are often valued far above maturity and wit, Estelle turned the tables.

She was an expert – a hands-on, old-fashioned, tough-conditions field worker – on the musical traditions of Mexico, Guatemala, and Puerto Rico and issued many of her field recordings on vinyl. Until the end of her life she was regularly invited to lecture in Mexico. Late in life, she also began an innovative internet-based study of music used by Neo-Nazis.

... It was your run-of-the-mill start of a new era; an era of Ruth as a lawyer, a teacher, a mentor, an activist. But it also marked a time during which Ruth's desire to have a family became uppermost. To really know Ruth is to know that her mantra is: Family First! That applies to her immediate family and her many extended families.

Never content to play only gay spaces, she would perform 'any place that would have her.' She loved being a bridge, helping others to gain confidence and find the resources they needed.

Waldman's activism manifested itself in her Jewish identity... She believed that the experience Jews had had in the world gave a very powerful link to work for tikkun olam, for social justice and peace, and fighting oppression. Though she considered herself a secular humanist and never belonged to a synagogue, she had a very strong network in the grassroots of the Jewish community and really believed in the power and beauty of Jewish culture and experience.

Roz was a more rounded person than I was. She didn't just love music, she played music. She didn't just appreciate art, she became a painter. She loved flowers, and planted them. She loved theater and took to the stage.

Her courage was more than physical: she had the courage of her convictions. Passionate about social justice, she did not stand on the sidelines. If a cause mattered to her, she dove in wholeheartedly, attending rallies, volunteering for Board service, arranging meetings, and organizing fundraisers.

She chose action over passivity. She chose to reform rather than to conform. Her diverse background and interests led her down many paths. As a renowned feminist, filmmaker, psychologist, educator, author, and activist who fully invested herself in every fiber of her work-literally, physically, metaphorically-Joyce touched the lives of many.

Willis brought lucidity and style to the most controversial and baffling cultural issues—her thought was a beacon of clarity. For those of us fortunate enough to have been her comrades, anticipating her insights was part of what kept us returning to meetings month after month, year after year.

The legacy that my mother left went beyond the immediate family. She was part of a great movement that profoundly changed American society. On a personal level, the legacy of her commitment inspired the succeeding generations of our own family. We, her children and grandchildren, remain committed to the beliefs of prophetic Judaism: to help the poor and the needy and to seek justice.

[A]n innovative and revered entrepreneur in the leather-armchair world of gentlemen antiquarian book dealers; unmarried in a world where women were wives, Stern lived in a universe in which it was not possible to live the way she wanted to. She simply ignored that impossibility, created her own universe and, in a small but exquisite way, changed the world.

Whether Hilda was sharing her moral outrage, her prodigious memory of historical events, handing out leaflets, or vigiling with Women in Black, she was for me a courageous and passionate teacher and activist.

Thinking about Barbara, I realize that she was a one-woman social networking site. She remembered everyone she had ever met and tried to connect them with everybody else she had ever met. She recalled where you were from, whom you dated, your health problems, and your writings or accomplishments and then she introduced to people who you should know.

…her hearing loss prevented her from hearing all of what she wanted to, but she turned that sorrow into her greatest gift—that of restoring human communication for others with hearing loss.

"She, in some ways, was way ahead of her time," said her daughter Margaret Shapiro, of Philadelphia. "Although she had a nice life, once it became nice, she really wasn't satisfied until she had a career of her own. And she wasn't from a family or a community that encouraged women to have careers of their own. But she stuck to wanting to have her own skills and her own career."

Lois' life was centered on the inherent goodness of humans and inherent humor of life. Everything she did was based on the principle that if you could make people laugh about the human condition, then you could make them do something to improve it.

... She was a rarity, a seemingly unstoppable spirit. Even as she was failing, she was working, unwilling to let go of the mission that had given meaning to her life, a mission shared by many but especially by me; to help bring about a change for the better in this often dismal world.

But even more, even more than I admired the stories, which was a lot, I admired Grace Paley's activism and her moral courage.

A daughter of immigrants and a working mother starved for time to write, Tillie Olsen drew from her personal experiences to create a small but influential body of work.

For those around her Emily served as a compass, both figuratively and literally. She knew how to help her community steer a clear course, guiding us with her own impeccable honesty and tenacious personality. You could also ask her for more practical directions and arrive with more clarity than mapquest can provide….

Ruth deeply believed that economic empowerment was the basis for increasing human rights and gender equity for women. If women have economic power, they gain confidence and courage, and become greater participants with increased voice in their communities. Everyone benefits when women benefit.

Even though she wanted to turn swords into ploughshares, she wielded her own kind of sharp weapon: an inveterate (and sometimes intimidating) intelligence. She had an eye for detail as well as a sweeping perspective that always saw the bigger, more critical picture….
