He earned his doctorate in 1912, under Kamerlingh Onnes, with a thesis entitled: Metingen over de compressibiliteit van waterstof, in het bijzonder van waterstofdamp bij en beneden het kookpunt. (Measurements on the Compressibility of Hydrogen).

On 22 December 1910 he married Geertruida Luberta Lorentz (20 November 1885, Leiden ), the eldest daughter of the physicist Hendrik Lorentz. They married

They got three daughters and one sons. They adopted a nephew, Johan Hendrik Mulock Houwer, born 15 May 1916 in Dordrecht Their birth dates were found in municipal records of Delft. He was raised Dutch Reformed but later became an atheist.
