Frederic Charles Danvers (1833–1906), often Frederick, was a British civil servant and writer on engineering.

[1] Born at Hornsey on 1 July 1833, he was second son of Frederick Samuel Danvers of Hornsey, an officer in the East India Company's service, and his wife Mary Matilda Middleton, daughter of H. Middleton of Wanstead, Essex.

[1] He attended the Exposition Universelle of 1867 in Paris, reporting in the Quarterly Journal of Science that other European nations were closing the technology gap with the United Kingdom.

In 1877 he was transferred as assistant secretary to the revenue department of the India Office, and was in January 1884 made registrar and superintendent of records.

[3] Work on the archive continued into the 1930s, but the scale was large, and projects, even though selective, were left incomplete.

His report, based on research in the Torre do Tombo archives and the public libraries in Lisbon and Evora, was published in 1892.

[1] His work on Portuguese records and history was recognised with the Order of Christ, knight commander.

[5] Danvers died on 17 May 1906 at Broad Oaks, Addlestone, Surrey, and was buried at All Saints' Church, Benhilton.

Sydney Ernest Fryer wrote in the Dictionary of National Biography that it "was marred by want of perspective and incomplete reference to authorities.
