Henry Bradbury

[1] Bradbury is known for his book The Ferns of Great Britain and Ireland with author Thomas Moore and editor John Lindley published in 1855.

It used the innovative technique of nature printing invented by Alois Auer and Andreas Worring in 1852 and improved by Bradbury.

The technique consisted of pressing a leafy specimen onto a thin, soft lead plate, leaving an intaglio impression with very fine detail.

From 1856 he took an interest in the security aspects of banknote printing, and set up the business Bradbury & Wilkinson.

[1] Bradbury had studied Auer's discovery in Vienna and had patented his own version in London.
