Weinbrenner, Friedrich an eminent German architect, was born at Carlsruhe in 1766. He was trained as a carpenter and builder, and in 1788 began to travel for improvement, visiting in turn Zurich, Dresdenn, and Berlin, and in 1792 started for Italy. Here he discovered his own want of training and instruction, and entered upon a thorough course of study and research, supporting himself in part by giving instruction in architecture to numerous persons, some strangers of distinction. He returned to Carlsruhe in 1797, where he became inspector of buildings, and soon after erected a synagogue and some private mansions. He removed to Strasburg two years after, but did not find much employment, and in a short time returned to Carlsrnhe in his former capacity. He entertained higher views of his art than his countrymen generally, and did much to diffuse the same sentiment throughout the next generation by his instructions. At Carlsruhe he constructed the Catholic church, Lutheran church, Theatre, Museum, Mint, Hochberg Palace, and other edifices. At Baden he supervised the erection of numerous buildings. He also constructed several churches, mansions, villas, etc., in various parts of Germany. He published a number of works on different branches of architectural studv, viz., Zeichnungslehre (1810): — Optik (1811 ): — Perspectivlehre (1817-24): — Ueber Form und Schouheit (1819): — Ueber architektonische Verzierungen (1820): — and other works. He died March 1, 1826.
