This classic history of American mathematics was first published in 1934. “America”, for the authors, is defined as the “territory north of the Caribbean Sea and the Rio Grande River.” This slim volume surveys the mathematics of the early colonial period including the knowledge available for the average colonist; the progress made corresponding to various influxes of population from Italy, France, Germany and Great Britain; the beginnings of mathematical work in colleges and universities and the rapid acceleration in the last quarter of the nineteenth century; the development and growth of a professional infrastructure of societies and publications; and biographical information of particularly significant characters. The book pays special attention to the needs of commerce, exploration, and everyday life that drove the development of mathematics in the centuries before a professionalization of mathematics appeared in the nineteenth century.
