Johann Baptist Isenring

Isenring, Johann Baptist (1796-1860), pioneering Swiss photographer. Trained originally as a carpenter, Isenring subsequently studied painting and engraving at the Munich Academy. As early as 1839 he experimented with Talbot's calotype process, but then switched to the daguerreotype, in November ordering a Giroux camera from Paris. In August 1840 he exhibited portraits in his native St Gall, then in Munich (October) and Augsburg (November). He achieved exposure times of c.6-20 seconds, and also began to colour his portraits. In 1841-2, after a period in Munich, he toured southern Germany, latterly with a transportable studio. He settled in St Gall in 1843, later earning a reputation as a graphic artist.

Johann Baptist Isenring (1796 - 1860) was a Swiss painter, printmaker and daguerreotypist. In 1840 or 1841 he produced the first coloured daguerreotype using a mixture of gum arabic and pigments. The coloured powder was fixed on the delicate surface of the daguerreotype by the application of heat. The result was one of the earliest examples of hand-colouring in photography.
