Wholesale Rulers of Science

12" Wooden Ruler made in U.S.A. of American-grown basswood. This ruler lists people who have made important contributions in any number of scientific disciplines: Medicine, Astronomy, Physics, Chemistry, Mathematics, Biology, Psychology, to name just a few. We have tried to find individuals whose contributions were important to mankind, and who came from various time periods, regions of the world and educational backgrounds. As you read through the list of names, you might notice several familiar terms. The words Fahrenheit (as in temperature), volt and ampere (electricity), daguerreotype (photography), Morse (like the telegraph code) and pasteurization all come from the names of scientists on the ruler. Women play an increasingly important role in the world of science. Marie Curie (1867-1934), Barbara McClintock (1902-1992), and Tu Youyou (1930- ) are all featured on Rulers of Science.
