Personal life In high school, Müller was only an average student. His grades suffered because he spent all his free time in his little home laboratory performing elementary experiments. In high school and college, Müller was often mocked by his peers being called, "The Ghost," due to his thin and pale appearance. Müller married Friedel Rüegsegger in 1927 and had two sons, Heinrich (b. 1929) and Niklaus (b. 1933), and one daughter, Margaretha (b. 1934). His wife took charge of the household and raised their two sons and daughter so that Müller could concentrate on chemistry. In his free time, Müller enjoyed the nature in the Swiss Alps and in the Swiss Jura where he owned a small holiday home, allowing him to resume his longtime interest in botany. Furthermore, he owned a small fruit farm that he regularly tended to. Müller often relaxed while gardening, photographing mountain wildflowers, and taking the children on early morning nature walks. Moreover, Müller and his wife often enjoyed playing flute and piano duets from Gluck's Orfeo ed Euridice. Reading on the weekends in the mountains, Müller immersed himself in the science of plant protection and pest control. This fascination resulted in his research on pesticides at Geigy, and sequentially the discovery of DDT's pesticidal properties. Müller was regarded as independent, a lone wolf. His daughter, Margaretha, called him an Eigenbrötler: one "who makes his own bread". He was determined and persistent in all aspects of his life, having learned a great deal from his college mentor Fichter. Müller died in the early morning of 13 October 1965 in Basel, after a short illness, surrounded by family. Honors Müller received many honors in his life, among them the Nobel Prize in Physiology or Medicine. Specifically Greece honored him for the near elimination of malaria in the country as a result of his discovery. In 1963, he was invited to Greece and received with great sympathy and celebrated as national hero.
