  abstract  = {The correspondence between Alexander von Humboldt und Karl Kreil was voluminous, it concerned earth magnetism. But only one letter has survived. This letter was written by Kreil on September 3, 1836; one day later Kreil wrote a letter to Carl Friedrich Gauss with nearly the same contents, some sentences are even literally corresponding. Four letters from Kreil to Humboldt were published in the „Annalen der Physik und Chemie". Some letters were mentioned in the biographical literature dealing with Kreil. These letters show, that the correspondence covered at least the period until 1851 and give information about the intensive relationship between the two scientists. A further interesting source is the library of Humboldt which unfortunately has not survived. The catalogue mentions nine works of Kreil some of them where annotated by Humboldt. This makes it plausible that the contacts even lasted until 1856.},
