Johan Ludwig Krapf (1810-81), a German-born missionary in Africa, is considered the father of Swahili studies in Europe. He created the first Swahili dictionary, which was published posthumously in 1882. This important lexicon also contains notes on Swahili culture and customs, together with an introduction to Swahili grammar.

Johan Ludwig Krapf (1810-81), a German-born member of the Church Missionary Society in East Africa, is regarded as the founder of Swahili studies in Europe. Having pursued an interest in Oriental culture from an early age, he first went to Abyssinia (Ethiopia) as a missionary. During his travels in Africa, he became the first European to see Mount Kenya; but he also considered the potential of Swahili as a lingua franca. Krapf published the first printed text in Swahili, and the first systematic Swahili grammar, as well as being the first to bring Swahili manuscripts to Europe. Another in a series of firsts is this lexicon, which was published posthumously in 1882. The Swahili dictionary, pioneering as it was in its day, is still of historical interest, especially because it contains notes on Swahili culture and customs, as well as an outline of the language's grammar.
