A HISTORICAL APPROACH TO THE EXCEPTIONAL LIE GROUP $G_2$ AND ITS GEOMETRY
This talk is devoted to a detailed historical and mathematical account of G2 s first years, in particular the contributions and the life of Friedrich Engel's almost forgotten Ph. D. student Walter Reichel, who worked out the details of the geometric description of G2 in 1907. I will also give an introduction to modern G2-geometry, its many impulses for modern differential geometry and its relevance in theoretical physics (superstring theory).
