History of chrysophyte research: origin and development of concepts and ideas

摘要

This account covers a period of about 200 years – from the early beginnings of light microscopy until electron microscopy became estab-lished in the middle of the twentieth century. It takes its beginning in the middle of the eighteenth century, in rural Denmark at idyllic Frederiksdal, a manor house 20 km north of Copenhagen. In 1750, Countess Catharina Schulin had lost her husband Count Johan Siegesmund Schulin, who had held a high position in the Danish government administration. She was left alone with two children, a large estate, and an enormous staff of servants. She sought comfort in religion and summoned young theology students from the University to preach for her (Anker 1943).
