Address given by Sir Charles Darwin at the Max Planck memorial service held on 23 april 1948 in the aula of the University of Göttingen
The University of Göttingen was founded by George Augustus, whom we know in England as King George II. He was Patron of the Royal Society, and it is fitting that in this hall the Royal Society should pay a tribute of reverence to the memory of the illustrious Max Planck. In his lifetime the Society recorded its deep appreciation of his services to science by electing him to the small and carefully guarded body of its Foreign Members and by bestowing on him in 1929 the highest honour which it has to offer, the Copley Medal. It is not necessary to-day to emphasize the importance of his profound and original researches. The quantum theory, of which he is the sole and undisputed originator, lies at the basis of all modern physical theory and the Society is happy to think that it numbers among its Fellows many who have helped to show how wide and how significant is its scope. Planck’s constant has taken its place by the side of Newton’s constant of gravitation as a symbol of a period of scientific revelation. But if Planck the originator in scientific achievement commands the homage of our heads, no less does Planck the man deserve the approbation of our hearts. His character was modest, kindly and blameless, and amid the trials of distressful times and through many personal sorrows he preserved his integrity and his quiet courage. The Society is happy to remember that Planck was its guest at the Newton Tercentenary Celebrations held in the summer of 1946, and that the many signs of respect and friendship that he then received clearly gave him pleasure in his declining days.
