Neil Sloane: the man who loved only integer sequences

Great to see this article about Neil, a warm and brilliant guy - I had the chance to meet him personally the last time the joint AMS meetings were in San Francisco.

Also, when I submitted a simple integer sequence[1] to OEIS on Thanksgiving Day a few years ago, he took the time that day to respond and educate me about some delightful related math.

The concept of the original published Handbook and the subsequent OEIS was pure genius. Almost no consequential objects in math can be easily looked up (i.e., ordered), but these sequences can.
