Adam Trimingham plainly does not know his sans serif from his elbow (The Argus, January 7).

Sans serif simply means "without serif" and it is Eric Gill's genius for lettering which allowed him to create a typeface of sans-serif block letters, which captured all the thick-and-thin, with-serif elegance of Trajan Roman.

In the article, Gill was portrayed standing in front of Trajan Romanstyle cut letters which, as with all Roman inscriptions, were cut with a chisel.

The mistaken belief he created sans serif fonts possibly belongs to Mark Dudeney and was simply perpetuated by Mr Trimingham's lack of knowledge about the work of Eric Gill.

I learned about design, form, shape, line, proportion and spatial relationship through a study of Gill Sans Serif as a 16-year-old apprentice in 1946 at Derby School of Art - a study which formed the basis of my work and artistic appreciation for the rest of my life.
