I was taught the correct way to do etching by a remarkable chap at Exeter College of Art and by a strange random web excursion I found a reference to him:
MAREK LACZYNSKI (Polish / 1925-)
Marek Laczynski was born in Warsaw. He was a partisan in WWII, while still in his teens. He left Poland after the Warsaw uprising in 1944, arriving in England with the Polish forces in 1946. He studied art at Borough Polytechnic and the Central School of Arts and Crafts. Marek Laczynski exhibited at the Grabowski Gallery, London, in 1960 and 1964. From 1964-1985 Marek Laczynski was Lecturer in Experimental Printmaking at Exeter College of Art and Design. Besides teaching at the college, Laczynski also published two books with the School of Printing’s private press imprint Bartholomew Books, The Wizard with his Pupil (1972), illustrated with original etchings, and Faces of Fear (1974), his own poems with reproduced etchings reminiscent of Fautrier’s Ôtages. Laczynski exhibited at Market Print Gallery, Exeter, in 1978. In 1981 he was one of ten artists who contributed prints to the Printmakers Council Portfolio, alongside Anthony Gross, Gertrude Hermes, John Piper and Julian Trevelyan. The British Museum has 9 woodcuts by Marek Laczynski in its permanent collection. Since 1985 Marek Laczynski has lived in Vienna.
