by Ridington, Thomas Tregoning
i: Manuscript on paper, text in pencil. 200 x 120 mm, 8 x 5 inches]. 26 [1] pp. Paper wrappers covers, sewn with binder’s cord; paper stock brittle at edges and a bit fragile. [Philadelphia, ca. 1905].
ii: Manuscript on paper, text in pencil. Geometric diagrams throughout. 225 x 170 mm., [9 x 6 ¾ inches]. 78pp. Card stock wrappers, ribbon ties for sewing, frayed and broken. [Philadelphia, ca. 1908].
Two manuscripts showing the development of a high school student from Prospect Park High School in Philadelphia. The progression in handwriting, the format of the two manuscripts, and the degree of difficulty of the mathematical materials covered demonstrates the growth in confidence of a student from freshman year to his final year in high school.
Book 1, Arithmetic for Children begins with a preface that reads in part, “This book is for children who are small and small numbers preferred. Definitions do not occur here because they are supposed to be already learned.” This is followed by the contents, which begins with Notations and Numeration divided into six parts. This is followed by fractions, decimals and answers at the end. Thomas Ridington is a very confident young man and marks the front and back covers with his monogram in overlapping letters, TTR.
Books II-V, Geometry: Ridington’s Senior class project on geometry, graded on the final leaf “100” in blue pencil. These four books he entitles “Constructions” and over the 78 pages provides examples, exercise, propositions, and proofs, each illustrated with diagrams precisely drawn and described.
Thomas Ridington graduated from Prospect Park High and attended University of Pennsylvania. After graduation he became an instructor in mathematics at Century High School in Philadelphia. . (Inventory #: 1270)
