In April 1958 he returned to Germany and began his studies at the Merz Academy in Stuttgart, where he attended a two-year program in applied graphic arts.

[4] As he later wrote, “When I began teaching in 1968, classical, so-called 'Swiss typography' (dating from the 1950s), was still commonly practiced by designers throughout Switzerland and at our school.

Its conservative design dogma and strict limitations stifled my playful, inquisitive, experimental temperament and I reacted strongly against it.

Through my teaching I set out to use the positive qualities of Swiss typography as a base from which to pursue radically new typographic frontiers.” [5] Between 1974 and 1996, at Hofmann’s invitation, Weingart taught at the Yale Summer Program in Graphic Design in Brissago, Switzerland.

For over forty years he lectured and taught extensively in Europe, North and South America, Japan, Australia and New Zealand.
