The Contributions of Lotfi A. Zadeh and Other Pioneers
by Rudolf Seising
I
n the 1960s, the discipline of computer science
(CS) emerged from electrical engineering (EE) and
research fields in mathematics and mathematical logic. Around the same time, fuzzy sets (FSs)
appeared as a new mathematical theory, founded by
the electrical engineer Lotfi Aliasker Zadeh. Some unpublished documents of Zadeh's show that the emergence of
CS and the theory of FSs were interlinked. Zadeh's task as
chair of the EE Department at the University of California,
Berkeley (UCB); his activities in the education of mathematics, EE, system theory, information theory (IT), and CSs;

and his creation of the theory of FSs generated his view and
choice of contents for the new discipline of CS as an FS.
Introduction
Science is the general analysis of phenomena in nature,
and that is what in ancient times was called natural philosophy. In the Middle Ages, scholars preserved the ancient
order of the subjects as the quadrivium (music, arithmetic, geometry, and astronomy) and, after the ninth century, the trivium of arts of humanities (grammar, logic,
and rhetoric). When universities emerged in the 11th centur y, these seven a r tes
liberales formed the facultas artium, joining the
