Initials Minus Full Stops in BrE?

Hi.

Is this acceptable? May I omit the full stops after M and F?

M F Nash or M. F. Nash (in BrE)?
(Short for Michael Francis Nash.)

And in BrE, 1 or 2 below in each?

Set 1

  1. Drs John D Smith and Irving L Johnson …
  2. Drs. John D. Smith and Irving L. Johnson …

Set 2
1. Profs Dean J Stevenson and Elouise F Cummings …
2. Profs. Dean J. Stevenson and Elouise F. Cummings …

Thank you.

Both forms of all those seem to be acceptable these days. There is a lot of support for simplification by leaving out unnecessary punctuation, particularly when it comes to titles.

Beeesneees, what’s your personal preference? I bet these are:

M F Nash (with spaces as shown here)
Drs John D Smith and Irving L Johnson …
Profs Dean J Stevenson and Elouise F Cummings …

Yes, when it comes to titles and names, I’m less of a traditionalist. A number of aspects of punctuation are now not so hard and fast, and are down to personal preference. In addition, the full stop after a title tends to be an AmE thing.
