Jan Tschichold was a German typographic designer who used san serif typefaces to create books. He was interested in graphic arts since he was 15 years old till he attended a teacher training institution and was encouraged to begin teaching graphic arts and book production when he was 21 years old. Tschichold was exposed to the modern movement in 1923, and he embraced his modern style until 1933, when his modern ideas were seen as perverted and decadent, and the Nazis dreaded his new radical typography and deported him to a concentration camp. Tschichold went through two significant style transformations during his career and legacy. He relocated to Switzerland, whereupon he entirely abandoned his prior approach and switched to serif fonts with center alignments, and where he wrote numerous books detailing his classical style of graphic design. He recognized the importance of his work and decided to move forward with it.

Karl Gerstner feels that problem solving is the best way to approach design. He enjoys being exact while designing since there is no margin for error when aiming to be rational. Gerstner also employs the usage of a tables while making designs; this table is used for double-checking to ensure that everything is in the correct position. Gerstner created this table and labeled each box with a potential solution, so that after he’s through with a design, he can simply check each category and see whether he received anything from them. He organizes with grids, which he claims assist him a lot. Although it appears to be complicated, he says it is simple to use once you get started.

Müller-Brockmann’s focuses on the grid. A well-designed grid improves typographic uniformity and helps with layout. They are utilized in webpages, posters, and postcards, and they are critical for maintaining legibility in multi-page periodicals and novels. Müller-Brockmann considers grid system literacy to be important for professional designers. This is a statement of a professional ethos: the designer’s work should be plainly comprehensible, objective, useful, and attractive in mathematical thinking quality. Working with the grid system entails conforming to universally recognized laws. Grids are a useful and necessary tool for generating consistent and well-thought-out design. They may appear to constrain originality, but they really provide a framework within which designers may express themselves while yet preserving enough order to be relevant to different mediums and contexts.
