Maria Reiche Grosse-Neumann (15 May 1903 – 8 June 1998) was a German-born Peruvian mathematician, archaeologist, and technical translator. She is known for her research into the Nazca Lines, which she first saw in 1941 together with American historian Paul Kosok. Known as the "Lady of the Lines", Reiche made the documentation, preservation and public dissemination of the Nazca Lines her life's work. She was widely recognized as the curator of the lines and lived nearby to protect them. She received recognition as Doctor Honoris Causa by the National University of San Marcos and the Universidad Nacional de Ingenieria in Lima. Reiche helped gain national and international attention for the Nazca Lines; Peru established protection, and they were designated a UNESCO World Heritage Site in 1994. Following her death, her former home in Nazca was converted into a museum, the Museo Maria Reiche. She is honored as the namesake of Maria Reiche Neuman Airport in Nazca, the Park Maria Reiche in Miraflores and of some fifty schools and other institutions in Peru. The 115th anniversary of her birth was commemorated with a Google Doodle in May 2018. Early life and education Maria Reiche was born in Dresden on 15 May 1903 to Felix Reiche Grosse and Ana Elizabeth Neumann. She studied mathematics, astronomy, geography and foreign languages at the Technische Universität Dresden. She learned to speak five languages. In 1932 as a young woman, she went to Peru to work as a governess and tutor for the children of the German consul in Cusco. In 1934, while still in Cusco, she accidentally stabbed herself with a cactus and lost a finger to gangrene. In 1939, she became a teacher in Lima and also worked on scientific translations. When World War II broke out that year, Reiche stayed in Peru. The next year she met American Paul Kosok, who was researching ancient irrigation systems in the country. She assisted him with making arrangements in the country, including a flight in 1941 by which she first saw the lines and figures of Nazca from the air. They collaborated for years on further studies of these earthworks, trying to determine how they were made and, with more difficulty, for what purpose.
