author
b. 1867
Best known for making the history of science approachable, this early 20th-century writer and teacher framed scientific progress as a human story rather than a list of facts. His most noted work, An Introduction to the History of Science, helped bring that wider perspective to general readers and students.

by Walter Libby
Walter Libby was an American author and educator born in 1867. He is chiefly remembered for An Introduction to the History of Science (1917), a work that presents science as a long, connected development across civilizations rather than a set of isolated discoveries.
The book itself identifies him as Walter Libby, M.A., Ph.D. and describes him as Professor of the History of Science in the Carnegie Institute of Technology, showing that he was writing from an academic background as well as for a broad reading audience.
Reliable biographical detail on his life appears to be limited in the sources I could confirm, but bibliographic records consistently place his lifespan as 1867–1955. What stands out most clearly is his role in helping early modern readers see science through history, biography, and big-picture explanation.
