Eminent and versatile Swiss-born American zoologist and geologist (1807–1873) who carried out much of his research as a longtime faculty member at Harvard, where he was also instrumental in building the university’s enviable natural history collection. ALS signed “L. Agassiz,” one page, 5 x 8, October 13, 1870. Letter to "Tom," in part: "Among the many things wanted in the Museum is a list of what we owe to other institutions or to individuals in the many exchanges received. Please ask every body in the Museum who has done anything in the matter to give you a list of what has been received in the course of the past year and what has been returned—what we owe and what is owed to us. It will be moreover useful to the Gentlemen in the preparation of this report for this year, which I will call in as soon as I return to Cambridge so that they ought to begin preparing for it." In fine condition, with some edge toning.Format: ALS
