I was invited to give a speech to the delegation of the Sun Yat-sen University earlier this week. Sun Yat-sen himself was a medical doctor who became the first president of the Republic of China, while the current president of the University, Professor Ning-sheng Xu, was a natural scientist.
Just for fun, and for some light relief, my colleague, Peter Chilton, and I decided to compile a provisional list of doctors or natural scientists who became presidents, prime ministers, (or equivalent), which we enclose below.
Please let me know if you have any other names to add to this list.
One thing is for sure, lawyers outnumber doctors and natural scientists combined by an order of magnitude.
