They announced that there will be a memorial service held by my university in 2 weeks.

Here is an excerpt that a former student of his and mentor of mine that I met through him wrote.

His passion for the field and desire to educate others was an inspiration to all of us. Most of us will remember him as the first person to capture our minds at XXXX. If it wasn’t for his slide shows or walking tours, most of us wouldn’t have found ourselves in his office enrolling in the major. His commitment to the students went above and beyond the duties of a professor. He became our friend, mentor and advisor.
