Favorite High School Memory:

Misbehaving in band rehearsals and getting yelled at by Mr. Reimer. (He had to stop puffing his cigarette when he yelled.)

What have you done since leaving high school?

I got an AB at Princeton in 1964 and a PhD in mathematics at UW (Seattle) in 1967. I met Sylvia Young (Bryn Mawr 1966) at a mixer in Princeton in 1964, and we were married in 1966.

My first job was at University of Wisconsin (Madison), where Sylvia got her Ph.D. in 1972. Then we both got jobs at University of Nebraska (Lincoln), and we're still there. In 2011 they made us an offer we could not refuse, and we both retired; but we are still doing most of the same stuff, just not getting paid. In fact, just this year I somehow acquired three new PhD students and took on associate editorship of another math journal.

For my son David's graduation present, I took him to Africa to climb Mt. Kenya (and drink beer). In 2008-2010 our daughter Andrea was teaching in Provence, France; she took me to various rock climbing venues --- Buoux, Orpierre, Gorge du Verdon, Chateau Vert. We also climbed Mt. Blanc together and tasted lots of fabulous wine. Last summer (2013) she whipped me into shape and I fulfilled a lifelong dream by climbing the Matterhorn.

I have graduated 17 Ph.D. students , all at UNL, and I wrote a book on Cohen-Macaulay modules (how interesting, you say!) with one of them. You can find the book on his website:

Current Interests:

My main non-academic interest is climbing (mountains and rocks). Occasionally, Sylvia talks me into running a trail marathon with her, though I have pretty much given up running, preferring to save what's left of my knees for climbing. Also, every year or so I work on playing the piano for a few weeks till I can stand listening to myself.

Middle Name or Initial:


Most Memorable Experience Since High School:

Falling through the roof of the Hotel Monterey in Huaraz, Peru, en route to a climbing trip in the Andes. I landed on the dining room table during lunch, after falling 24 feet. Don't try this at home, but the fall fixed my lower back, which had been bothering me a lot up till then.

One Thing I Have Done Since High School That Would Surprise My Classmates:

Considering my total lack of athletic ability in high school (special gym for asthmatics and otherwise handicapped folks, a timed 2-minute quarter mile in my junior year, etc.), some might be surprised that I have managed to crank out several marathons in under 2:50 and even survived three 100-mile trail runs (Superior Trail Run twice and the Hardrock once).

Things That I Haven’t Done as of 2011, But Would Still Like To Do. Record when you do them plus comments.

Climb the Matterhorn. [Done, summer 2013. Perfect, cloudless weather, great fun!]

Still hoping, as of 2014:
Complete 100 ascents of Longs Peak (14 to go).
Publish 100 math papers (19 to go).
Maybe Climb Ama Dablam. (Probably won't happen; it's getting too dangerous, thanks to climate change.)

I do hope you'll consider doing another via ferrata in the Dolomites. Most of them are pretty safe --- and lots of fun. (I do several every year.)
