author
1865–1945
An early physician-writer who helped bring psychotherapy to general readers, she co-authored a practical guide to nervous disorders at a time when mental health was rarely explained in everyday language. Her work is still remembered mainly for making complex ideas feel approachable.

by Josephine A. (Josephine Agnes) Jackson, Helen M. Salisbury
Josephine A. Jackson, also listed as Josephine Agnes Jackson, was an American physician and author born in 1865 and died in 1945. Reliable library and catalog records connect her most clearly with Outwitting Our Nerves: A Primer of Psychotherapy, a 1921 book she wrote with Helen M. Salisbury.
That book was written for a broad audience rather than a specialist one, explaining psychotherapy and nervous disorders in plain, reassuring language. Because of that accessible style, Jackson remains of interest to readers looking at early popular writing on mental health and self-understanding.
Some biographical details about her training and career appear online, but the available sources I could confirm here were strongest on her identity, dates, and authorship rather than on a full life story. For that reason, this overview keeps to the parts that can be supported confidently.
