Very parochially UK-relevant only, but I am amazed that this guy was so influential and slightly surprised I had not come across him before. Another unsung hero who had profound effects on the lives of those of us in the British masses…
Loved him in Superman
Ailsa Land - another person unheard of except in specialist domains. I do enjoy reading reading about these less well-known people who were nevertheless giants in their field. (Though not enjoying the fact they are obituaries.)
The “branch and bound” method that Land devised with her colleague Alison Doig (later Alison Harcourt) in 1960 “reshaped the landscape of mathematical programming”, in the words of the Operational Research Society. It is now a fixture of courses in maths, computing and statistics that have applications to real-world problems, and continues to be deployed in engineering, logistics and military operations.
true to her calling, Land managed her time optimally so that she could enjoy both family and career.
