Barbara Probst Solomon, an American memoirist and essayist known for documenting life in Spain during and after the regime of Gen. Francisco Franco, died on Sunday at her home in Manhattan. She was 90.

The cause was renal disease, her family said.

Esteemed by critics for her observations on 20th-century culture and politics, Ms. Solomon was renowned in particular for her 1972 memoir, “Arriving Where We Started,” which chronicled her youthful involvement with the anti-Franco resistance movement, including her naïvely brazen rescue of two resistance members from a Spanish labor camp.

Her essays appeared in The New York Times, The New Yorker, The New Republic, HuffPost and elsewhere. She was also a novelist and a translator from the Spanish.

Reviewing “Arriving Where We Started” in The New York Times, the Harvard literary scholar Robert Kiely wrote, “A picture of a credible and strong‐willed young woman emerges: a kind of earnest picaresque heroine, shrewd, resilient, generous, game for adventure, and absolutely committed to life.”
