[1][2] Born in Halland, Sweden, Skoog emigrated to the United States during a trip to California in 1925, and was naturalized as a citizen almost a decade later.
In 1937, Skoog was a postdoctoral researcher with Dennis Robert Hoagland, and his professional career advanced significantly with his arrival at the University of Wisconsin–Madison in 1947.
Carlos O. Miller discovered kinetin in 1954,[4] and benzyladenine and related compounds were later synthesized in Skoog's lab.
In 1962, Skoog and Toshio Murashige published what is probably the best-known paper in plant tissue culture; in a fruitless attempt to discover a yet-unknown plant growth regulator in tobacco juice for his doctoral thesis, Murashige and Skoog instead developed a greatly improved salt base for the sterile culture of tobacco.
[5] Now 60 years after the work, M&S salt base remains an essential component in plant tissue culture, but not in hydroponics.
