PEHR KALM. Pehr Kalm (6 March 1716 – 16 November
1779) was a Swedish-Finnish explorer, botanist, naturalist, and
agricultural economist. He was one of the most important apostles of Carl
Linnaeus. Among his many accomplishments, Kalm can be credited for the first
description of Niagara Falls written by someone trained as a scientist.
PEHR ADRIAN GADD. The first real professor of chemistry
was Pehr Adrian Gadd who was appointed in 1761 following the separation of
chemistry from agriculture. Gadd was born in 1727 in Pirkkala, and was educated
at Åbo. In 1749, after becoming a Magistrat, Gadd became Docent. He took the
place of Kalm while the latter was visiting America. In 1758 he was appointed
assistant to the professor, but because he wished it so, he received no salary.
Gadd showed a decided interest for the applications of science to practical
life; he devoted much of his experimental work to technical, mineralogical, and
agricultural chemistry, rather than to the theoretical.
PETTER FORSSKÅL. Peter Forsskål (11 January 1732
- 11 July 1763) was a Swedish explorer, orientalist, naturalist and an apostle
of Carl Linnaeus. Peter Forsskål was one of those pupils of Carl Linnaeus who
lost their lives on expeditions in distant lands. He was the naturalist member
of the famous Arabian Expedition (1761-1767), sent by Denmark to study the
nature and culture of Yemen, “Arabia Felix” of olden times.
