Museum expert Rachel Morris had been ignoring the boxes under her bed for decades. When she finally opened them, an entire bohemian family history was laid bare. The experience was revelatory - searching for her absent father in the archives of the Tate; understanding the loss and longings of the grandmother who raised her. Transported back to the museums that had enriched her lonely childhood, Rachel also explores the stories of the early museum makers, whose passions and mistakes were reflected in her own family.
