Karl von der Mühll was born on September 13, 1841 in Basel, Switzerland. He was a Swiss mathematician and physicist. He was born into the Von der Mühll family, of the Basel patriciate (see Daig), to Karl Georg and Emilie Merian, of the Merian family, a granddaughter of Peter Merian. He was president of the Swiss Euler Commission (and thus editor of Leonhard Euler's works) and published Franz Neumann's lectures on electrical currents in 1884. From 1872 he was co-editor of the Mathematische Annalen. In 1875 he married Katharina His, daughter of Eduard His, also of the Basel Daig.
