From a Crossref Blog Post by Ed Pentz:
In my blog post on January 14th about Crossref’s 20th anniversary I said, “The one constant in Crossref’s 20 years has been change”. It’s true that there has been constant change, but there has been another constant at Crossref –– me (and DOIs, to be fair). I started as Crossref’s first employee and Executive Director on February 1st, 2000, so I just marked my 20th anniversary with the organization.
This milestone prompted me to reflect on where I am and where I’m heading. After 20 years leading the organization, I’ve decided to leave Crossref. It’s time for a new challenge. I’m still very committed to the mission and very proud of my time at Crossref, the culture we’ve created and what the organization has achieved. It’s been an honor serving as Executive Director and a pleasure working with so many great people over the years. And to be clear –– I’m not ill, being pushed or having a midlife crisis (yet).
