Anne Penfold Street died this week.
Anne arrived at the University of Queensland as a lecturer while I was a student there. She taught me measure theory; a feature of her well-organised lectures was that all results were numbered in sequence, so that we reached Theorem 100 before the end of the course.
But her main field was combinatorics, where she wrote several books: an introduction, a book on combinatorics of experimental design with her daughter Debbie, and research monographs.
Anne was very active in the combinatorics community, as president of the Combinatorial Mathematics Society of Australia (a sister body of the BCC) and recipient of their medal, and as president of the ICA.
She was the third female professor of mathematics appointed in Australia, and the Australian Mathematical Society has an award named after her.
