Myra North, Special Nurse was written by Ray Thompson and drawn by Charles Coll. The strip, which was distributed by the Newspaper Enterprise Association, debuted on February 10, 1936. A Sunday page was then added December 6, 1936. Thompson and Coll continued to work on both strips until they folded a few years later.
One thing to be aware of, is that Myra North is not quite the person you would imagine. Although she is indeed a nurse, Myra spends a large proportion of her time investigating spies, super-criminals and other miscreants. So the strip is most definitely not a medical soap opera.
In 1938 Myra appeared in a Big Little Book, but that was about her only outing away from her newspaper strips. The daily ended on March 25, 1939, but she continued to make regular appearances on Sundays until August 31, 1941. And that was the end of Myra North!
