HENKY EDWARD SCHUNCK. 18201903. 



Henry Edward Schunck was born in Manchester, August 16, 1820. 

 He was the youngest son of Martin Schunck, who, settling in Man-

 from Germany he entered his father's calico-print works, but after a 

 few years he retired from business, and resolved to devote his life to 

 pure science. 



It was in Liebig's laboratory that Dr. Schunck made his first 

 investigations on the colouring matters contained in certain lichens 

 from which archil and cudbear were prepared, and he succeeded in 

 isolating the crystalline substance lecanorin, whose composition and 

 relationships he determined. 



His first paper on colouring matters was communicated to the 

 Chemical Society in 1841, a few months after the founding of the 

 Society, of which he was elected a Fellow in the same year. This 

 research is typical of much of the work which Dr. Schunck afterwards
