At the end of the two years in Zurich, Auguste went to the commercial house of his uncle at Neuchâtel, and Louis to the University of Heidelberg, taking letters of introduction from Professor Schinz and others. Professor Tiedemann, the chancellor, had studied with Schinz; therefore, Agassiz received a warm welcome, and an offer of books from his library. The young student worked earnestly. He wrote to his father: "Every morning I rise at six o'clock, dress and breakfast. At seven I go to my lectures given during the morning.... If, in the interval, I have a free hour, as sometimes happens from ten to eleven, I occupy it in making anatomical preparations.... From twelve to one I practise fencing. We dine at about one o'clock, after which I walk till two, when I return to the house and to my studies till five o'clock. From five to six we have a lecture from the renowned Tiedemann. After that, I either take a bath in the Neckar, or another walk. From eight to nine I resume my special work, and then, according to my inclination, go to the Swiss Club, or, if I am tired, to bed. I have my evening service and talk silently with you, believing that at that hour you also do not forget your Louis, who thinks always of you." At Heidelberg, like Humboldt, Agassiz needed a congenial friend, and found one in Alexander Braun, of Carlsruhe, an ardent lover of botany, afterward Director of the Botanical Gardens in Berlin. He wrote to his parents concerning Agassiz, "a rare comet on the Heidelberg horizon.... Not only do we collect and learn to observe all manner of things, but we have also an opportunity of exchanging our views on scientific matters in general. I learn a great deal from him, for he is much more at home in zoölogy than I am. He is familiar with almost all the known mammalia, recognizes the birds from far off by their song, and can give a name to every fish in the water. "In the morning we often stroll together through the fish market, where he explains to me all the different species. He is going to teach me how to stuff fishes, and then we intend to make a collection of all the native kinds. Many other useful things he knows; speaks German and French equally well, English and Italian fairly, so that I have already appointed him to be my interpreter on some future vacation trip to Italy. He is well acquainted with ancient languages also, and studies medicine besides." Schimper, another brilliant botanist, was a friend of both Braun and Agassiz. The professor in zoölogy, Leuckart, was very fond of these bright pupils, and allowed himself to be gotten up at seven in the morning, to give them extra lectures.
