Hermann von Helmholtz fu un erudito poliedrico il cui lavoro abbracciò la medicina, la fisica e la filosofia. In fisiologia e psicologia, esplorò la matematica della visione, le teorie della percezione e la sensazione del tono, basando le sue intuizioni sull'osservazione empirica e modelli matematici. Le sue ricerche in fisica indagarono la conservazione dell'energia e i fondamenti meccanici della termodinamica. Come filosofo, contemplò la relazione tra le leggi della natura e la percezione umana, sostenendo il potere civilizzatore dell'indagine scientifica.

An annotated edition of fifty-three letters by Hermann von Helmholtz to his fiancée and later wife, Olga von Velten. Never previously published in complete form, these documents provide the most comprehensive autobiographical account of the young Helmholtz. In 1847, Helmholtz was a surgeon for the Prussian army in Potsdam, seeking to become a scientist. By 1859, he had become a professor in the medical faculty at Heidelberg and one of Europe's leading sensory physiologists. These letters thus span the formation of Helmholtz's university career and the development of his cultural, political and philosophical worldview. The letters are given in German, introduction and annotations in English.
