Friedrich Melchior, Baron von Grimm was a German-born French-language journalist, art critic, diplomat and contributor to the Encyclopédie ou Dictionnaire raisonné des sciences, des arts et des métiers. In 1765 Grimm wrote Poème lyrique, an influential article for the Encyclopédie on lyric and opera librettos. Like Christoph Willibald Gluck and Ranieri de' Calzabigi, Grimm became interested in opera reform. According to Martin Fontius, a German literary theorist, "sooner or later a book entitled The Aesthetic Ideas of Grimm will have to be written."

Christian Johann Heinrich Heine was a German poet, writer and literary critic. He is best known outside Germany for his early lyric poetry, which was set to music in the form of lieder by composers such as Robert Schumann and Franz Schubert. Heine's later verse and prose are distinguished by their satirical wit and irony. He is considered part of the Young Germany movement. His radical political views led to many of his works being banned by German authorities—which, however, only added to his fame. He spent the last 25 years of his life as an expatriate in Paris.

Gottfried Wilhelm (von) Leibniz was a prominent German polymath and one of the most important logicians, mathematicians and natural philosophers of the Enlightenment. As a representative of the seventeenth-century tradition of rationalism, Leibniz developed, as his most prominent accomplishment, the ideas of differential and integral calculus, independently of Isaac Newton's contemporaneous developments. Mathematical works have consistently favored Leibniz's notation as the conventional expression of calculus. It was only in the 20th century that Leibniz's law of continuity and transcendental law of homogeneity found mathematical implementation. He became one of the most prolific inventors in the field of mechanical calculators. While working on adding automatic multiplication and division to Pascal's calculator, he was the first to describe a pinwheel calculator in 1685 and invented the Leibniz wheel, used in the arithmometer, the first mass-produced mechanical calculator. He also refined the binary number system, which is the foundation of nearly all digital computers, including the Von Neumann machine, which is the standard design paradigm, or "computer architecture", followed from the second half of the 20th century, and into the 21st.

Oskar Pastior was a Romanian-born German poet and translator. He was the only German member of Oulipo.

Albert Schweitzer was an Alsatian polymath. He was a theologian, organist, writer, humanitarian, philosopher, and physician. A Lutheran, Schweitzer challenged both the secular view of Jesus as depicted by the historical-critical method current at this time, as well as the traditional Christian view. His contributions to the interpretation of Pauline Christianity concern the role of Paul's mysticism of "being in Christ" as primary and the doctrine of Justification by Faith as secondary.
