He was of German origin, and was born in Pomerania. His parents wanted him to go in for the church, but after two years at the University of Wittenberg he determined to live the life of a scholar. At Wittenberg, Ruhnken lived in close intimacy with the two most distinguished professors, Heinrich Ritter and Berger. To them he owed a thorough grounding in ancient history and Roman antiquities and literature; and from them he learned a pure and vivid Latin style. At Wittenberg, Ruhnken also derived valuable mental training from studying mathematics and Roman law.
The only thing that made him want to leave was a desire to explore Greek literature. Neither at Wittenberg nor at any other German university was Greek being seriously studied at the time. It was taught to students in divinity for the sake of the Greek Testament and the early fathers of the church. Friedrich August Wolf was the real creator of Greek scholarship in modern Germany, and Richard Porson's gibe that "the Germans in Greek are sadly to seek" had some truth in it. The state of Hellenic studies in Germany in 1743 was such that their leading exponents were Johann Matthias Gesner and Johann August Ernesti. Ruhnken was advised by his friends at Wittenberg to go to the University of Leiden, where, stimulated by the influence of Richard Bentley, the great scholar Tiberius Hemsterhuis had founded the only real school of Greek learning on the Continent since the days of Joseph Justus Scaliger and Isaac Casaubon.
Hemsterhuis and Ruhnken had the closest possible friendship during the twenty-three years between Ruhnken’s arrival in the Netherlands in 1743 and the death of Hemsterhuis in 1766. A few years made it clear that Ruhnken and Valckenaer were the two pupils of the great master on whom his inheritance must devolve. As his reputation spread, many efforts were made to attract Ruhnken back to Germany, but after settling in Leiden, he only left the country once, when he spent a year in Paris, ransacking the public libraries (1755). For work achieved, this year of Ruhnken may compare even with the famous year which Ritschl spent in Italy.
In 1757 Ruhnken. was appointed lecturer in Greek, to assist Hemsterhuis, and in 1761 he succeeded Oudendorp, with the title of "ordinary professor of history and eloquence", as Latin professor. This promotion attracted the enmity of some native Netherlanders, who deemed themselves more worthy of the chair of Latin. Ruhnken's defence was to publish works on Latin literature which eclipsed and silenced his rivals.
In 1766 Valckenaer succeeded Hemsterhuis in the Greek chair. The intimacy between the two colleagues was only broken by Valckenaer's death in 1785, and stood the test of common candidature for the office (an important one at Leiden) of university librarian, in which Ruhnken was successful. Ruhnken's later years were clouded by severe domestic misfortune, and by the political commotions which, after the outbreak of the war with England in 1780, troubled the Netherlands without ceasing, and threatened to extinguish the university of Leiden.
Ruhnken was not in any way a recluse or a pedant. He had good looks, attractive manners, and an open unpretentious personality. He was sociable and cared nothing for rank. His biographer says of him in his early days that he knew how to sacrifice to the Sirens without proving traitor to the Muses. Life in the open air had a great attraction for him; he was fond of sport, and would sometimes devote to it two or three days in the week. In his bearing towards other scholars Ruhnken was generous and dignified, distributing literary aid with a free hand, and meeting onslaughts for the most part with a smile. In the records of learning he occupies an important position, as a principal link in the chain which connects Bentley with the modern scholarship of the European Continent. The spirit and the aims of Hemsterhuis, the great reviver of Continental learning, were committed to his trust, and were faithfully maintained. He greatly widened the circle of those who valued taste and precision in classical scholarship. He powerfully aided the emancipation of Greek studies from theology; nor must it be forgotten that he first in modern times dared to think of rescuing Plato from the hands of the professed philosophers--men presumptuous enough to interpret the ancient sage with little or no knowledge of the language in which he wrote.
