Some years ago, I studied mathematics and statistics. At that time, there was only one statistician among the mathematics department members, maybe the entire Swarthmore College faculty, **Gudmund R. Iversen**. He was my academic adviser. Professor Iversen was grey, tweedy and Norwegian. He always addressed me as Miss Kesselman, which helped alleviate my shyness at the time.

Professor Iversen got his PhD in statistics from Harvard University in 1969. I noticed only one other familiar name on that very short **list of all Harvard Statistics PhD alumni:** Columbia University political science and statistics professor **Andrew Gelman PhD in 1990**.

### Lunch with Tufte

Professor Iversen had a group of colleagues, all statisticians from other academic institutions. They would visit Swarthmore to give lunchtime talks, or more typically, late Friday afternoon presentations to mathematical statistics students.

I recall one particular guest statistician. Edward Tufte was on the faculty of Princeton University, and had recently written his first book, *The Visual Display of Quantitative Information*. The venue was a small private room in Sharples dining hall. I was one of maybe 20 attending. (more…)
