And I was (in my mind) pronouncing your last name 'zee-ber' - assuming false Germanic pronunciation authority. (Serves me right!)

As for Adler, though I am familiar with the Irene Adler reference (as which Holmesian would not be?) the first thought I had was of the psychologist/psychiatrist Adler - wasn't he the third in the holy trinity begin by Freud and Jung?

And, no, I would not dream of pronouncing (or spelling) the name 'Alder' (being perhaps more likely to 'correct' it the other way - from Alder to Adler...)
