Amsterdam, 1962, p. 311) wrote of Magnus and his co-worker De Kleyn: ‘The examiner [1927] declared that the work done by Magnus and De Kleyn clearly deserved a prize, and the prospects for an award seemed most favourable when Magnus unexpectedly died.’ For his life and work see, Rudolf Magnus, Physiologist and Pharmacologist: A Biography (2002, Royal Netherlands Academy of Arts and Sciences) by his son, Dr.Otto Magnus.
Magnus had five children, Karl (1903-1989) lung specialist; Margarete (Gretl)(1905-1968)who worked as his secretary and translator; Dorothea who died aged 11; Erica (1909-1991) architect; and Otto (1913-2014) neurologist.
