Elizabeth Baker (c. 1720 – c. 1797) was an English secretary, diarist, and amateur geologist.
[2] She moved to Wales in 1770 to prospect for metals in the Dolgellau area of Merionethshire, but did not have the financial support of her partners to be able to complete the endeavour.
Baker then lived in Bryn Adda for about six years, followed by Dolgellau.
She documented her experiences in ten diaries, which were held by the National Library of Wales and excerpts were published in its journal.
[2][b] Identified as Mrs. Baker, her papers and diaries from the period from 1740 to 1798 were archived at the National Library of Wales.
