This book grew out of my research on the history of mathematics over the past
40 years. Time and again, the path of my investigation led me to the consideration
of work by Frobenius that played an important role in the historical development
I was attempting to understand. I finally decided it would be appropriate to bring
these research experiences together into a book on the mathematics of Frobenius,
especially since little has been written about him despite the fact that he made many
important contributions to present-day mathematics—as suggested by the many
theorems and concepts that bear his name.
