My professional name on papers, email signatures, etc. is almost always D. Andrew Brown. I’ve always found unnecessary initials, suffixes, etc. to be a little pretentious. It’s no surprise, then, that I am ambivalent about including the “D.” in front of my own name. However, in official directories, class bulletins, and most legal documents, I show up as “Derek Brown” or “Derek A. Brown.” This has caused confusion in the past when people come around looking for Derek Brown, and they find Andrew, so I just use the initial to (hopefully) make it clear that we are one and the same. There also are A LOT of Andrew Browns in the world, and I hope that “D. Andrew Brown” makes distinguishing me from the rest a little easier.
