Diary of a traveler from Vienna, Austria, with the surname Rehn to the United States in 1869. The author describes his travel to cities in the Middle Atlantic and Midwest regions--Washington, Philadelphia, New York, Pittsburgh, Cincinnati, Cleveland, and Chicago. He comments on the technology (factories, machines, railways, etc.) and architecture (bridges, buildings, social facilities, etc.) he sees. The diary contains a variety of sketches, including sketches of buildings, floor diagrams, bridges, etc. Also included are a travel diary for a trip to Italy in 1875; four engravings of Viennese buildings, 1856-1875; and two geological maps, 1866-1873. In German.

A wealthy retired businessman and art collector from New York and Newport, R.I., Theodore M. Davis financed a series of archeological excavations in Egypt between 1889 and 1912. Avid, but not necessarily disciplined in his approach, he supported a remarkably productive series of excavations at Thebes and, in the work for which he is best remembered, in the Valley of the Kings. On many of these expeditions, Davis was accompanied by his relative, Emma B. Andrews. The diary that Andrews kept during these expeditions is valuable on two scores. First, at its best, it provides a literate and often detailed record of an adventurous American woman traveling in fin de siecle Egypt and (to a lesser degree) Italy and her encounters with life in the colonial British settlements along the Nile. Second, it provides some important details on the appearance of tombs in the Valley of the Kings as they were first unearthed, with interesting comments upon Davis and a number of his fellow Egyptologists.

These two diaries were kept by Amelia Smith Calvert on trips to Europe with her husband Philip Powell Calvert. They record little scientific information, although there is mention of some of the entomologists and scientists whom they met (e.g. Professor Robert Newstead of University of Liverpool). In general, her observations are those of a literate and passionate sightseer who records travel events in great detail. The British diary (1912) includes descriptions of Liverpool, Edinburgh, York, Lincoln, Cambridge, Oxford, and London, and observations of the entomological specimens they saw in London. The Europe diary (1929) includes descriptions of Antwerp, Brussels, Amsterdam, Lucerne, Venice (of particular interest), Padua, and Milan. There is a description of P.P. Calvert's examination of insect specimens in the collection of Baron de Sélys-Longchamps in the Institut royal des sciences naturelles de Belgique.

Ernst Krackowizer (1821-1875), father-in-law to the anthropologist Franz Boas (APS 1903), was an Austrian born surgeon who fled Vienna to New York following his involvement as captain of the Academic Legion during the Revolution of 1848. Krackowizer was an active member of New York medical community, helping to found the German Dispensary and Hospital, later renamed Lenox Hill Hospital. During the Civil War, Krackowizer assisted the Union Army as a volunteer surgeon and inspector of military hospitals. Krackowizer is claimed to have been the first on whom the anesthetic effects of chloroform were tested in Vienna and the first to use a laryngoscope in the United States. This collection is comprised of the personal papers of Ernst Krackowizer including diplomas, certificates, correspondence, diaries, and photographs, which document his life and medical career. Krackowizer's experience in the Revolution of 1848 and subsequent flight from Vienna trough Germany to the United States is well detailed in his correspondence to his fiancée and later wife, Emilie Forster, and in his diaries, which make up a significant portion of this collection. Krackowizer firsthand description of the early use of chloroform and the laryngoscope are included, as well as materials documenting his involvement as a volunteer surgeon and hospital inspector during the Civil War. Additionally, the Krackowizer Papers contain material written by others reference the life and work of Ernst Krackowizer.
