History Graph theory is a branch of mathematics which studies the structure of graphs and networks. Graph theory started in 1736, when Euler solved the problem known as the Konigsberg bridges problem. 2. WebGraph theory in chemistry. The value of graph theory to chemistry started to become apparent in the 19th century. Work by two British mathematicians, Arthur Cayley (1821-1895) and James Joseph Sylvester (1814 -1897), laid the ground for a long tradition of successful use of graph-theoretical ideas in chemistry.
