Keet (rhymes with Fiat, not seat) was born on 20 June 1885 in the town of Alice in the Eastern Cape Province.
He attended school first in Humansdorp, were his father was a preacher (c. 1894) and later in Cape Town (De Beer 1992:10).
The congregation in Humansdorp had the option of attending an evening service in English twice a month and young Bennie, as he was known, was friends with the son of the local "English preacher", despite the looming threat of the Anglo-Boer War (Second Boer War).
De Beer is of the opinion that Keet's friendship with English-speaking children, with their differing language, beliefs and habits, helped to develop his relatively liberal character (1992:14), (1992:15).
Keet attended the South African College School (SACS) in Cape Town during that war and then completed studies for the degree of Bachelor of Arts at the South African College, in the same city.
In 1907 he entered a theological college, where he was involved in the management of the Afrikaans Language Union (De Beer 1992:10–21, 33).
From January 1911 to 1913 Keet was enrolled at the Free University in Amsterdam, where he worked towards a doctorate under the guidance of Herman Bavinck (De Beer 1992:40–41).
