My given name is David. Family members still call me that. Everybody else calls me Doc. Since people often ask me where that nickname came from, and since apparently I haven’t answered it anywhere I can now find online, here’s the story.
Thousands of years ago, in the mid-1970s, I worked at a little radio station owned by Duke University called WDBS. (A nice history of the station survives, in instant-loading 1st generation html, here. I also give big hat tip to Bob Chapman for talking Duke into buying the station in 1971, when he was still a student there.)
As signals went, WDBS was a shrub in grove of redwoods: strong in Duke’s corner of Durham, a bit weak in Chapel Hill, and barely audible in Raleigh—the three corners of North Carolina’s Research Triangle. (One of those redwoods, WRAL, was audible, their slogan bragged, “from Hatteras to Hickory,” which is about 320 miles as the crow flies.)
As a commercial station, WDBS had to sell advertising. This proved so difficult that we made up ads for stuff that didn’t exist. That, in addition to selling ads, was my job. The announcer’s name I used for many of the ads, plus other humorous features, was Doctor Dave. It wasn’t a name I chose. As I recall, Bob Conroy did that. I also had a humorous column under the same name for the station’s monthly arts guide, with the image above at the top of the page. That one was created by Ray Simone.
Ray and David Hodskins, another WDBS listener, later approached me with the idea of starting an ad agency, which we did: Hodskins Simone & Searls. Since we already had a David, everybody at the agency called me Doctor Dave, which quickly abbreviated to Doc. Since my social network in business far exceeded all my other ones, the name stuck. And there you have it.
