Undated memoir of life of physicist Lev Landau by his niece. She describes her memories of his personality and physical presence: how he was opinionated, boisterous and unconventional, and his love of poetry and argument; his political beliefs; his parents and family life; her own relationship with him and his influence on her career; his relationship with the women in his life and his family; his serious car accident which led to his death in 1968.
