Lodewijk Willem John Karel Thomson was born on 11 June 1869. His father was a navy medical officer, his mother was a Pompe van Meerdervoort, a family of the lower nobility. The family lived in Voorschoten (left on A). After completing the three-year pre-university high school curriculum, he enrolled in the Royal Military Academy in Breda in 1884 (B). Commissioned as a second lieutenant of infantry in 1888, he was posted to the Nijmegen garrison. His promotion to first lieutenant followed in 1892. In that same year, Thomson was inducted into the Order of Freemasons under the Grand East of the Netherlands. See the old lodge in Egyptian style (C).
