Throughout this whole article all I could think of is how was Erle Stanley Gardner writing in a magazine that ran from 1882 to 1891. when he was born in 1889. He was a very advanced toddler I suppose.
But maybe you saw that and were just making a joke? In which case, I'll just <whoosh> myself.
> To help investigate his cases, Gardner assembled a committee of crime experts, including a private detective, a handwriting analyst, a former prison warden, and a homicide specialist with degrees in both medicine and law. They examined dozens of cases between September of 1948 and October of 1958
So, the magazine was active from 1892 to ~1986. At some point, which appears to be between 1948 and 1958, Erle Stanley Gardner headed the feature in question.
