That thread was somewhat helpful, although most of the links no longer work.
Wonder whatever happened to that OP?
Anyway, it kicked me in the head to search on Grindell Matthews. Although that only turns up two threads, and I’ve found more mentions that than just poking around myself.
But one of the threads is 1920s style death rays? HALL OF FAME NOMINATIONS where some guy posts a long article giving me much of what I need to know. Thanks, guy from the distant past I no longer remember.
Oh, and something I’ve wanted to say for a long time. Just a general plea, maybe a reminder that should go into a sticky. Don’t just post a bare link with no information. Give us something that a) makes it searchable on the Dope and b) makes it findable on Google if the links goes dead at a later time.
The example I’m looking at in that thread is:
Which guy? What site? What article? The link is now dead.
That happens all the time. It would be really helpful for people to put the name of the article and site into the link and quote a bit of the text so that we aren’t clicking blindly.
