Stella Court Treatt (English Wikipedia)

Admittedly the Treatts were beaten by the "Croisière noire" (Citroën central Africa expedition). The expedition was known as the croisière noire (fr. "black cruise") and initiated by André Citroën. It was led by Georges-Marie Haardt and his deputy Louis Audouin-Dubreuil and included Léon Poirier, Georges Specht, Eugène Bergognier, Charles Brull, and Alexandre Iacovleff. They crossed the continent from north to south and arrived in Cape Town in 1925. The Citroën expedition was undertaken with specially adapted Half-track Citroën Type B2 lorries, which were more like tanks than motor cars.
