During the past forty years string theory has made great progress, but string theory can be recognized in the West mainly due to John H. Schwarz. This paper aims to study the figure Schwarz who play a pioneering, groundbreaking figure role in the development of string theory. Although Schwarz's work attracted the attention of the physical world, but there is no research on the scientific achievements, thinking and methods of Schwarz. Therefore this article is to fill the Research gap on Schwarz.From Schwarz's Research Course of string theory, this article mainly discusses Schwarz's contributions and ideas that promoted the process of string theory development before the first superstring revolution. This paper is divided into four parts:Chapter 1 is an overview of Schwarz's life and scientific work. In Chapter 2 the important scientific achievements of Schwarz are described in details and analysed philosophically. Chapter 3 summarizes the basis of Schwarz's scientific thinking, and explores the reasons for the success of Schwarz's research. Chapter 4 explores how Schwarz get the achievements.
