New Yorker cartoonist Amy Kurzweil’s efforts to connect to people in her own past led her to write and illustrate two graphic family histories. The first tells the story of her mother’s mother, who escaped the Holocaust without any photos or personal records, only her memories—many still fresh in her now-97-year-old head. Her father’s father, profiled in Kurzweil’s latest book, left an abundance of records and writings but died long before the cartoonist was born. Two very different lives to reconstruct. Two very different challenges in storytelling.
