Biography
Johann Albert Heinrich Reimarus (11 November 1729 – 6 June 1814) was a German physician, natural historian, and economist who became a well-known figure during the Enlightenment. Born in Hamburg to the philosopher Hermann Samuel Reimarus, he grew up in a family that valued intellectual pursuits. His sister Elise was a well-known writer, showing the family's dedication to learning.
Reimarus studied medicine and natural sciences and went to London in 1755 to learn about anatomy from the respected British anatomists William Hunter and James Douglas. This experience exposed him to the latest medical techniques and scientific methods, which he later introduced to Europe. During his time in London, he also learned about innovations like the lightning rod, which he brought back to Germany.
After returning to Hamburg, Reimarus worked as a physician and was a strong advocate for public health. His key medical achievement was introducing smallpox vaccination to Hamburg, which saved many lives when the disease was widespread. He also promoted the use of lightning rods in Europe, reflecting his dedication to applying scientific knowledge for public benefit.
Reimarus married twice. His first marriage resulted in a daughter, Johanna Reimarius, who later married Georg Heinrich Sieveking. After his first wife's death, he married Sophie, the sister of August Adolph von Hennings. This second marriage connected him to important circles in German intellectual society. Besides medicine, Reimarus was interested in economics, natural history, and entomology, showing the wide-ranging interests characteristic of Enlightenment scholars. He spent his final years in Rantzau, where he died on 6 June 1814, having lived through significant political and social changes of his time.
Before Fame
Growing up as the son of Hermann Samuel Reimarus, a major figure in Germany's Enlightenment movement, Johann Albert Heinrich was immersed in intellectual conversations from a young age. His father's work as a critic of traditional Christianity and supporter of natural religion created a home environment that fostered questioning established beliefs and seeking empirical knowledge. Living in Hamburg's merchant society, along with his family's academic background, naturally steered him toward the medical sciences.
The mid-18th century saw rapid progress in medical knowledge, especially in anatomy and surgical techniques. Acknowledging the superior training offered in London, Reimarus made the important decision to study abroad in 1755, aiming to learn from top British anatomists who were introducing new approaches to medical education and practice.
