Sudoku Garden

This week’s Sudoku Garden celebrates the life of Professor William Stearn, who died 25 years ago today. Stearn was born in 1911, and left school 15 years later, taking a job at Bowes & Bowes bookshop in Cambridge. It was here where he read his way into botany while working in the shop. He would go on to become one of the titans of the field. Stearn's most famous book is Botanical Latin. Until very recently, every new species had to be described in Latin, a language most botanists had to wrestle.
