About the author

Born on September 29, 1848, and dying on June 29, 1925, David Nunes Carvalho was an American specialist in ink, handwriting, and questioned documents. He became known as an expert witness in important legal disputes, using close study of writing and ink to investigate whether documents were genuine.

For readers today, his most lasting work is Forty Centuries of Ink (1904). The book ranges widely through the story of ink, mixing historical research, practical observation, and the kind of curiosity that makes a technical subject feel accessible.

Carvalho's career sits at an interesting meeting point of science, law, and book history. That blend gives his writing a special appeal: he was not just describing old materials, but showing how they mattered in real life, from manuscripts and printing to forgery cases and forensic analysis.
