Carl Linnaeus the Younger

Swedish naturalist (1741–1783)

Uppsala University enrolled Carl Linnaeus the Younger as a student when he was nine years old. As the son of a pioneering taxonomist, he navigated a career defined by the academic shadow of his father, eventually succeeding him as the head of Practical Medicine in 1763 without the standard requirement of defending a formal thesis.

Academic Ascent and Institutional Conflict

His early education was overseen by his father's prominent students, including Pehr Löfling, Daniel Solander, and Johan Peter Falk. His rapid elevation to professor at age 22 occurred without traditional examinations. This unconventional path to seniority generated significant friction and professional resentment among his university colleagues, who viewed the appointment as a departure from meritocratic standards.

Botanical Research and Publication

His primary contributions to the field of botany focused on the refinement and documentation of existing systems. His most significant academic effort, the 1781 work Supplementum Plantarum systematis vegetabilium, functioned as an edited compilation of descriptions originally drafted by his father and various contemporaries. This volume provided critical additions and structure to established botanical records.

European Travels and Final Years

Between 1781 and 1783, he undertook a two-year tour through England, France, the Netherlands, and Denmark. While stationed in London, he contracted jaundice, a condition that compromised his health. Shortly after returning to Sweden, he suffered a fever followed by a fatal stroke. He died at the age of 42 at the Uppsala Cathedral Assembly and was buried within the family grave at Uppsala Cathedral.

Legacy of Scientific Collections

He managed an extensive collection of scientific correspondence, specimens, and books inherited from his father. Following his death in 1783, these assets remained in the family until his mother, Sara Elisabeth, sold the library and herbarium to English botanist Sir James Edward Smith in 1784. The materials eventually transitioned to the Linnean Society of London through the actions of Smith's widow, Pleasance Smith.
