[1] According to Harry W. Laidler, the government under Schermerhorn's premiership "achieved important results in the fields of labor, finance, housing, old age pensions, and the social services".

[5] Schermerhorn remained professor until 1944, when he was removed by the German occupational forces because of his activities in the Dutch resistance.

Schermerhorn was the first Dutch Prime Minister who appointed civil servants with a political background, people like Koos Vorrink and Hendrik Brugmans (nicknamed "The Schermerboys").

His brother, Dirk Schermerhorn [nl], was an engineer in the Soviet Union (he was involved in the construction of the Moscow Subway).

His sister, Neeltje, was married to theologian Johannes Marie de Jonge, principal of the Theological Seminary of the Dutch Reformed Church in Driebergen (1960–1968).
