I am looking for studies/ dissertations on the pioneer graphic designers in the modern era. How can I conduct a thesis on a specific graphic designer? What is the approach taken? How is the analysis? etc..
sadly for your interesting proposal there is a problem. On the whole research into graphic design or industrial design does not have a long tradition to draw on. The area parallel to yours in architecture is much more established. You might find looking at that body of work gives you some methodological help. You could even look at my book Design in Mind which is a study of a dozen famous architects. I’m sure the same approach could be followed in your area. Good luck.
Note that, the post-postmodern era of Theorizing and design of the data and fact-based .In order to theoretically understand the types of design methods and their classification, I have done some research. The root of the difference in the type and quality of design using modeling tools or even in BIM Methods technology is in the theoretical difference and the process of definition and problem solving. I suggest you read the following research. In the future, I will publish this research in the form of a book.
The most theoretically sound book is Rand Thoughts on Design 1970. He makes the most interesting points about graphic design process and knowledge. I presume you know that reference.
The problem solving view of designing is rather outdated now and while it still provides some insights the newer ways of analysing design are proving more productive.
A major problem that has arisen in architecture since modernism has been the unintended separation of theoretical foundations from the design process. Because the theoretical foundations up to that time contained tradition, philosophy, and aesthetics based on the immortality of reason, while modernism completely rejected them. In contrast, it moved the design process toward functionalism and standard patterns based on prefabrication and industrial production. Reducing the architecture to a global and modernist style and being satisfied with its aesthetic principles could not replace the theoretical foundations of architecture in the former sense. One aspect of the critique of modernism in architecture is the reduction of the place of theoretical foundations to physical and technological frameworks. In postmodernism, systemic thinking and many methods based on the achievements of environmental psychology tried to replace the theoretical foundations based on traditions. Although this period led to the growth in the field of organizing and structuring the knowledge and experience and skills of architects in the face of high environmental information, but still in postmodernism, design research seeks to place design in a process based on theoretical foundations Is; As in those traditions, the main theme and achievements of environmental psychology, as a theoretical framework. Design issues are therefore no longer considered as independent, parallel, or purely non-theoretical steps.
