Margareta Magnusson, the 91-year-old Swedish artist and author, died Thursday in Gothenburg, Sweden, leaving a legacy tied to her best-selling book *The Gentle Art of Swedish Death Cleaning*. Her work, inspired by the Scandinavian practice of *dostadning* (tidying up in preparation for death), urged readers to declutter homes and lives as a way to ease the burden on loved ones. Published in 2018, the memoir-manual hybrid sold over 1 million copies worldwide, translated into more than 30 countries, and sparked a Peacock home improvement series starring Amy Poehler.
