Lazzaro Spallanzani

Italian priest, biologist and physiologist (1729-1799)

Lazzaro Spallanzani worked in botany at a period when the field was still deciding what counted as an answer.

Lazzaro Spallanzani was born at Scandiano in 1729. He was educated at University of Bologna.

The eighteenth century turned natural philosophy into organised enquiry: expeditions, collections, academies and the beginnings of specialist training.

His working life was spent at University of Modena and Reggio Emilia and University of Pavia, where the work centred on biology.

Botany turned the sprawling variety of plant life into ordered knowledge that agriculture and medicine still draw on.

The range is worth noting. Lazzaro Spallanzani published across botany, zoology, natural history and palaeontology - a breadth that was ordinary in this period and has become almost impossible since.

What that record amounts to is a body of botany that later workers could build on without re-checking. That is the practical test of a scientific life, and it is a harder one than fame.

Lazzaro Spallanzani died in 1799, aged 70. What survives is not the reputation but the result: the part of botany that no longer has to be argued for.
