Paul Hermann Müller born at
He married Friedel Ruegsegger in 1927 and had two son, Heinrich and Niklaus and one daughter, Margaretha from the marriage.
Paul Hermann Muller died on October 12, 1965 in Basel, Switzerland.
Paul Herman Muller was born in Olten, Solothurn, Switzerland on January 12, 1899. His father, Gottlieb Muller, was an official of the Swiss Federal Railways and his mother was Fanny Leopold.
He was the oldest of the four children in the Muller family.
He spent most of his early childhood in Lenzburg, in Aargau, but had to move to Basel at the age of five when his father was transferred there. After moving to Basel, Muller attended a primary school.
He attended the ‘Freie Evangelische Volsschule’ elementary and secondary schools later.
In 1916 he worked as a laboratory technician for a brief period in the chemical factory of Dreyfus & Company.
On May 25, 1925 Muller joined as a research chemist in the dye division of the firm ‘J. R. Geigy’ which produced synthetic dyes, plant-based dyes and tanning agents that were available in nature. He remained with this company for the rest of his life.
In 1930 he developed synthetic tanning agents and dyes which remained fast under sunlight.
In 1935 he started a study on insecticides that could affect insects coming into contact with them. He stressed upon the various criteria of a perfect insecticide that would make it cheap, highly stable for long periods, prove highly potent against all types of insects without causing any harm to plants, animals or humans.
In 1937 he developed and patented a method for producing insecticides out of synthetic cyanate and rhodanide based compounds.
He also developed a mercury-free seed disinfectant called Graminone which benefited the Swiss farmers a great deal at the time.
Paul Hermann Muller’s investigations in ‘Uber Konstitiution und Toxische Wirkung von naturlichen und neuen synthetischen insektentotenden Stoffen’ written with H. Martin and P. Lauger came out in ‘Helevetica chimica acta’ in 1944.
His paper with the title ‘Uber Zusmmenhange zwischen Konstitution und insektizider Wirkung’ was published in 1946.
He gave an account of the discovery of DDT in ‘Dichlorodiphenyltrichloroathan und neuere Inzekticide’ which was published in 1949.
