In 1853 an Austrian printer, Alois Auer, published a book describing a nature printing processes which he had patented in 1852. It was from this publication that the English printer Henry Bradbury learned how to print his two volumes - one on British Seaweeds and the other on Ferns, published in 1855. Bradbury apparently patented his method of printing without any acknowledgement to Auer, from who he had learned the basis of it. In the ensuing controversy, when Auer accused him of being a drunkard and a liar, Bradbury became depressed - perhaps also affected by working with so much lead - at the age of 29 committed suicide by drinking prussic acid mixed with soda water.
