Ipmb100

I’m a regular reader of TIME magazine. Every year they publish an issue devoted to the TIME100: the hundred most influential people of that year. I thought I would do the same, except I’d focus on Intermediate Physics for Medicine and Biology. So, below is a list of the one hundred scientists, physicians, engineers, and mathematicians who most influenced IPMB. I list them by impact, with the most influential first.

Like for the TIME100, selecting the list is not an exact science. It’s based on mentions in IPMB, numbers of citations, and my own personal opinions. I’m sure your list would be different, and that’s okay.

There are many brilliant scientists who didn’t make the list (for example: Newton, Faraday, Maxwell, Rutherford, and Einstein). I tried to focus on people who had a direct impact on IPMB, rather than fundamental but not biomedical contributions to physics, so these and other luminaries were left off. 

The oldest scientists are Brown (born 1773) and Poiseuille (1797). The youngest are Basser, Goodsell, Hämäläinen, LeBihon, MacKinnon, Mattiello, Strogatz, and Xia (all more or less my age). I’m embarrassed to say there are only three women (Curie, Eleanor Adair, and Mielczarek; four if you count Abramowitz’s coauthor Stegun). Thirty three are alive today. Twenty are Nobel Prize winners (marked with an asterisk). I know ten personally (marked with a §). When I wasn’t sure about the year a scientist was born or died, I guessed and marked it with a question mark. There are many more I would like to honor, but I decided to—like TIME—stop at 100.

Enjoy!
