Derek J. de Solla (Derek John de Solla) Price

Born in London in 1922, Derek J. de Solla Price first trained as a physicist before moving into the history of science, a shift that shaped the rest of his career. He taught at Yale University and became one of the best-known scholars in the field, bringing unusual energy to subjects that ranged from medieval instruments to the growth of modern research.

Price is often described as a pioneer of scientometrics because he studied science itself as something that could be measured and analyzed. His books, including Little Science, Big Science, helped popularize ideas about the rapid expansion of scientific research and the networks that connect scholars, while his work on the Antikythera mechanism drew wide attention to the sophistication of ancient technology.

Across his writing, he had a gift for showing that charts, machines, manuscripts, and citation patterns could all tell stories about how knowledge is made. He died in 1983, but his work still stands out for connecting the history of science with big questions about innovation, evidence, and the structure of scholarly life.
