Anna Strunsky was born March 21, 1877, into a Jewish family in Babinots (now Babinovitch), Liozna Raion, Russian Empire (now Belarus). She and her parents, Elias Strunsky and Anna Horowitz, emigrated to New York City in 1886 when she was nine years old. Her several siblings included an older brother Max and a younger sister Rose, with whom she was close. After several years in New York, in 1893, the family moved to San Francisco. They moved in with her older brother Max, already established in the city as a doctor.

Anna joined the Socialist Labor Party as a teenager and remained a socialist the rest of her life. She studied at Stanford University (1896–1898). While at Stanford, she met the young writer Jack London, and they became close friends. She and London spent a great deal of time together discussing social and political issues.

Strunsky and her sister Rose, who also attended Stanford, became leading members of the turn-of-the-20th century San Francisco intellectual scene, part of a radical group of young Californian writers and artists known as The Crowd. It included George Sterling and his wife Caroline "Carrie" E. (née Rand) Sterling, Herman Whitaker, Ambrose Bierce, Richard Partington and his wife Blanche, Joseph Noel (dramatist, novelist and journalist),^[1][2] Joaquin Miller, Arnold Genthe and the hosts, Jack London and his wife, Bessie Maddern London, and Xavier Martinez and his wife, Elsie Whitaker Martinez, and others.^[3]

With Jack London, Strunsky wrote her first novel, The Kempton-Wace Letters, in the epistolary style. They published it anonymously in 1903.^[4] After his death in 1916, Strunsky published a memoir of her relationship with London.^[5]

In 1906 Strunsky and her sister Rose joined American socialist William English Walling in Russia as correspondents for his revolutionary news bureau. They were reporting on the failed revolution of 1905. He was an independently wealthy man from Kentucky who became a socialist and progressive. Anna and William married that year, returning to the United States at the end of the year. Based in New York City, they traveled and reported together on the Springfield race riot of 1908 in Illinois, and called for an effort in the North to deal with racial discrimination. They had four children together before separating about a decade later. Walling was among the co-founders of the National Association for the Advancement of Colored People (NAACP) in 1909, along with W. E. B. Du Bois and Mary Ovington.

Strunsky continued her writing while living in New York, and her second novel, Violette of Père Lachaise, was published in 1915.^[6] Around the same time, she and her husband moved to Greenwich, Connecticut and she joined the Woman's Peace Party.^[7] William and Anna separated during the Great War, in part due to their disagreement over the United States' role in the conflict; William supported US intervention as necessary to defeat the Central Powers and left the Socialist movement, which was anti-war.

Strunsky continued to write and advocate for socialism. She participated in Quaker social activity, and was an active member of several liberal-left groups, including the War Resisters League, the League for Mutual Aid, the American League to Abolish Capital Punishment, and the League for Industrial Democracy.

Strunsky died on February 25, 1964, in New York. She was survived by her four children, Rosamond, Anna, Georgia and Hayden Walling. Hayden, an architect known for his work on Cape Cod, died in 1981.^[8] Rosamond (1910–1999) became a painter who was married to Edward Corbett at the time of his death.^[9]
