About the author
Born in Leipzig on February 13, 1822, Johannes Rudolf von Wagner studied and worked across several German cities before continuing his chemistry studies in Paris at the Sorbonne in the mid-1840s. He later returned to Leipzig, earned his doctorate, and built a career that combined chemistry with technology and applied industry.
Wagner taught in Nuremberg and then at the University of Würzburg, where he became a professor of technology. Reference works on his life describe him as both a chemist and a chemical technologist, and his best-known books, including Handbuch der chemischen Technologie and the widely translated Manual of Chemical Technology, were valued for explaining industrial chemical methods clearly and in detail.
He died in Würzburg on October 4, 1880. Although not a household name today, his writing helped shape how chemical technology was taught in the 19th century, bridging the gap between laboratory science and large-scale production.
