About the author

Best known as an American expert on ink and handwriting, he built a reputation in the late 19th and early 20th centuries as a specialist whose knowledge could be used in legal disputes over documents and signatures. He was born on September 29, 1848, and died on June 29, 1925.

His most famous book, Forty Centuries of Ink (1904), traces the long story of ink from the ancient world to modern industrial production. The book is more than a technical manual: it mixes historical curiosity, practical explanation, and the perspective of someone deeply interested in how writing materials affect authenticity, preservation, and the truth of a document.

He is also remembered as a collector and bibliophile, with his name attached to catalogues of rare books and incunabula. That combination of forensic expertise, historical learning, and love of books gives his writing a distinctive appeal for listeners interested in science, history, and the hidden life of documents.
