Annie MacMillan Knott (1 September, 1850 – December 20, 1941) was a practitioner and teacher in The First Church of Christ, Scientist.

While in the London area and acting on a long-held desire to help the sick,[4] she did volunteer work in local hospitals, although she was herself in poor health with bronchitis and other ailments.

One afternoon, when this child was approaching his second birthday, Knott heard him screaming in the kitchen and discovered he'd swallowed much of a bottle of disinfectant, carbolic acid.

The child was soon relieved from pain and the next morning, recovered completely, helping himself to an apple he found in the pantry.

She had already purchased the Christian Science textbook and had been reading it; after the experience with her son, she began a more intensive study of the book, during which she found her health improving.

Her letter, along with those from Maybury, James E. Scripps, D. Augustus Straker and more than 50 others, was sealed in a metal box at midnight on December 31, 1900.
