Leonhard Euler and the Bernoullis

A K Peters
Number of Pages: 

This is an interesting and entertaining biography of Leonhard Euler (1707–1783) and of some of the Bernoullis, aimed at middle and high school students. The scientific content is skimpy; the book emphasizes day to day life and the relations between the mathematicians, especially the forever-squabbling Bernoullis. On the Bernoulli side nearly all the attention goes to Euler’s contemporary and colleague Daniel (1700–1782) and to Johann (1667–1748), Daniel’s father and Euler’s teacher. Johann’s elder brother Jacob (1654–1705), a teacher of Euler’s father Paul and a fierce rival of Johann, gets a moderate amount of coverage.

The book is somewhat fictionalized. How fictionalized? The book focuses on conversations and day to day life of the characters in Basel and in St. Petersburg, and because this material is generally undocumented, the author has invented most of the details. There is no bibliography and no footnotes, but as a guess I would say only about 25% of the book is traceable to actual historical documents. I’m not enthusiastic about this approach; it’s probably harmless for a book intended to interest children in science, but it’s not scholarly.

Although most of the book is not literally known fact, it is plausible and consistent with what we do know. Some letters are quoted in paraphrased form, and there is a large amount of dialog, nearly all of which must have been invented by the author. The style of the dialog varies wildly, with some of it using up-to-date slang and some reading like the most stilted Victorian children’s literature.

There are a number of illustrations, both historical etchings and present-day photographs of places mentioned in the book, and a detailed index. Unfortunately there’s no “further reading” section, so if a child’s interest is ignited by this book he won’t know where to go. (Actually children do know where to go — Google — but that’s not always the best choice.) I think E. T. Bell’s Men of Mathematics, although old and criticized for its own looseness with historical fact, is still valuable and would be a good next book. Ioan James’s Remarkable Mathematicians is a modern version of Bell’s book, and is more accurate but less exciting. William Dunham’s Euler: The Master of Us All is aimed at an audience that’s a few years older than Tent’s is, but it does have a nice biographical sketch and a much more thorough description of Euler’s mathematical work.
