Author:
Christian Friedrich Schönbein (1799-1868), German-Swiss chemist who discovered and named Ozone and invented the fuel cell
Publication details:
‘June, 1842’ and ‘Manchester’.
The signature - ‘Schonbein / June, 1842’ - is on a 4 x 1.5 cm slip of greyish paper, laid down over the bottom left-hand corner of a 10 x 6 cm piece of the same, carrying the address ‘To the President of the Chemical Section of the [British] Association / Manchester’. The slip with the address is in its turn laid down on a piece of paper cut from a leaf of an autograph album. There is some difference between the handwriting of the signature, which is looser, and the address, which is more formal; and whether hte latter is also by Schönbein is unclear.
