I see from a comment on one of the other posts that Professor Federico Cheever, a beloved environmental law professor at the University of Denver, passed away recently on a family trip. Cribbing now from the memorial notice at the University of Denver:
On June 10, 2017, our friend and esteemed colleague Fred Cheever died suddenly while vacationing in his beloved state of Colorado.
Federico Cheever was Professor of Law at the University of Denver Sturm College of Law. After graduating from Stanford University (B.A./M.A. 1981) and UCLA (J.D. 1986), and clerking for Judge Harry Pregerson of United States Court of Appeals for the 9th Circuit in Los Angeles (1986-1987), he came to Denver as an Associate Attorney for the Sierra Club Legal Defense Fund (1987-1989). With a few exceptions, he has been in Denver ever since. In 1990, he briefly commuted to Boulder to be a Research Fellow at Natural Resources Law Center, University of Colorado School of Law. Between 1990 and 1993, he was an associate at the law firm Faegre & Benson, in Denver, doing commercial and environmental litigation. He began teaching at the University of Denver College of Law in 1993 specializing in Environmental Law, Wildlife Law, Public Land Law, Land Conservation Transactions and Property. Professor Cheever served as the Hughes/Rudd Research Professor at the University of Denver College of Law in 2002. He briefly left Denver again in 2000 to be a Visiting Fellow at Queen Mary and Westfield College, University of London. He served as a Visiting Professor at Northwestern Law School, Lewis & Clark College during the summer of 2005. In 2007 he was a visiting research fellow at the Australian National University in Canberra, ACT. From 2005-2007 he served as an adjunct professor at the Colorado School of Mines, teaching Environmental Law. In 2006 he was selected DU Law Star for excellence in teaching. In 2011, the students of the College of Law chose Professor Cheever the Most Outstanding Faculty Member for that year.
Here in the faculty lounge Professor Cheever and his family are in our thoughts.
I believe this story provides more details about the sad and untimely death of Professor Cheever.

I think it's Federico, not "Frederico."
