The History of Approximation Theory From Euler to Bernstein

From the reviews:

"This book aims to tell the historical evolution of the methods and results of approximation theory, starting from the work of Euler in 1777 on minimizing distance errors in maps of Russia, and of Laplace in 1843 on finding the best ellipsoid for the earth, and ending with the work of Bernstein. The central character in the book is Chebyshev (1821–1894) and the Saint Petersburg Mathematical School he created.... [The] book contains much interesting material and has certainly motivated me to learn more about the subject and its history. No book can wish for more and so I recommend the book to anyone interested in approximation theory or in the history of mathematics."

"The author describes the early stage of development of approximation theory. … The famous Russian school founded by … Chebyshev is presented in full. … contributions of German and French mathematicians to both Weierstrass and Chebyshev directions are illuminated … . All this is supported with quotations from documents, letters, speeches, early publications, and memoirs. … Undoubtedly, the author has succeeded in catching the spirit both of the Russian atmosphere of that time and of the depth and richness of the human relationships … ." (B. Boyanov, Mathematical Reviews, Issue 2006 j)

“The discussion of mathematical results and ideas constitutes the main part of the book—always accompanied by moving stories, marked by devotion to science, by humanity, and often by the cruelty of the political turbulence of Russian history. Undoubtedly, the author has succeeded in catching the spirit both of the Russian atmosphere of that time and of the depth and richness of the human relationships of the people involved.”(MATHEMATICAL REVIEWS)

"This nice little book is devoted to the early development of approximation theory. It mainly concentrates on the role of Russianmathematicians but confronts it with the development of approximation theory in the West … The book will be of interest for historians of mathematics and for specialists in approximation theory." (EMS Newsletter, September, 2006)

"The storie is vivid, rich and touching. Many interesting details from the life, education and work of the unsurpassed master of classical analysis, Sergei Natanovich Bernstein, are given. Some of them are published for the first time and come from personal reminiscences of his pupils, close friends and collaboratiors. ...All this is supported with quotations from documents, letters speeches, easrly publications, and memiors. ... Undoubtedly, the author has succeeded in catching the spirit both of the Russian atmosphere of that time and of the depth and richness of the human relationships of the people involved." (American Mathematical Society)

"The book’s stated goal is ‘to describe the early development of approximation theory… (until) 1919….’ I learned lots of new names, new stories, and new connections. … In conclusion, this book is necessary … for studying the history of approximation theory. … it does contain plenty of useful information that is not readily or not at all available elsewhere."
