How a German diplomat invented the modern scientific peer review process in London

In short: Henry Oldenburg, a 17th-century polyglot and diplomat, transformed the landscape of science. As the first secretary of the Royal Society, he pioneered the practice of sending manuscripts to experts for evaluation before publication. This simple editorial innovation birthed the modern scientific journal and remains a cornerstone of global research today.

Born in Bremen around 1618, Henry Oldenburg was a theologian and linguist who arrived in London in 1653 as a diplomatic envoy. His intellectual trajectory shifted as he integrated into the city's elite circles, befriending figures like Robert Boyle and John Milton. By the time the Royal Society was founded in 1660, Oldenburg had positioned himself as a central hub for European intellectual exchange, taking on the role of the society's first secretary.

Oldenburg’s most enduring contribution was the founding of the Philosophical Transactions of the Royal Society. To ensure the quality of the work published, he introduced the practice of submitting manuscripts to independent experts for review. This mechanism, designed to vet scientific claims, evolved into the peer review system that governs academia today. The journal he established continues to operate, holding the title of the world's longest-running scientific publication.

Beyond his editorial work, Oldenburg was a master of correspondence, maintaining a vast network that included thinkers like Baruch Spinoza, whom he introduced to the scientific writings of Boyle. His life was not without peril; during the Second Anglo-Dutch War in 1667, he was briefly imprisoned in the Tower of London on suspicion of espionage, partly due to his role in supplying intelligence to the politician Sir Joseph Williamson. Despite these political entanglements, his commitment to the Republic of Letters remained his defining legacy.

Oldenburg died in 1677 at his home in Pall Mall, leaving behind a structure for scientific communication that transcended national borders. By formalizing how knowledge was shared and scrutinized, he helped transition science from a collection of isolated discoveries into a collaborative, self-correcting global enterprise. His work remains the bedrock of how we validate and disseminate human knowledge.
