Kannemans received his first lessons from painter Jacob Bernardus Frederiks (1790-1827), son of the previously discussed Jan Hendrik Frederiks (1751-1817). He married Delphina van Dooremael at the age of 19 and earned a living as a house painter and glazier. Over time he developed into a painter, but is mainly self-taught. In 1840 he dared to do it, partly on the advice of the well-known Hague painter of church interiors Johannes Bosboom (1817-1891) and supported by the chairman of the Breda Chamber of Commerce J.A. van der Burgh, to devote himself completely to painting. His shop is turned into a studio. In 1843 he participated for the first time in exhibitions of works by Living Masters in Zwolle and Antwerp. His work was shown in Breda in 1845. Apparently these exhibitions did not go unnoticed because General Baron H.G. Nahuys van Burgst (1782-1858), owner of the Burgst estate near Breda, and King Willem II (1792-1849), enabled him to make study trips to England and along the French and Dutch coast. Kannemans specializes in sea scenes, river and harbor views.
