Via David Ing:

I received a message that Ian Mitroff passed away on June 17, from his spouse Donna Mitroff .

For the community at the International Society for the Systems Sciences, where he was president in 1992, he returned in the 2010s and 2020s to guide a next generation of hashtag#SystemsThinking learners, extending the work of C. West Churchman.

I was lucky enough to speak to Ian a few years ago, and found him intelligent, amusing, and a font of wisdom.

This obituary from his daughter is nice:

Remembering Ian Mitroff, founder of the field of crisis management
