R.I.P. Heinz

I just learned that Mr.
Heinz Bohlen passed away this morning. He is famous among microtonalists for the discovery of the so called Bohlen-Pierce scale.
I only met him through the internet and he always looked as a very nice person, as when he asked a “connection” to me on Linkedin:

Linkedin Heinz

or when he commented on a
review I had written of a book by Easley Blackwood.

A brilliant human being!

May he rest in peace.
