Frederick Jacomb, a barrister based in Huddersfield, was one of the original members of the Alpine Club of London. He took part in several notable climbs: in 1860, he accompanied Leslie Stephen on the first crossing from Zermatt to Saas, climbing the Alleleinhorn; in 1861, he joined William Mathews in the first ascent of Monte Viso. Descriptions of his climbs were included in the second series of Peaks, Passes, and Glaciers (1862), and articles by him appeared in the first two volumes of the Alpine Journal. The present defective copy of the first series belonged to Jacomb, who made more than sixty annotations to certain of the essays. Many of these are personal recollections of climbs made during two seasons (1855, and again in 1860), several of them being quite extensive - in two instances, his notes run over three or four pages. His comments range from the terse - “True” often appears alongside a description - to personal expressions. He notes guides that have accompanied him on his own climbs: Octonier; “Kronig” [presumably Johann Kroneg]; Simond; and Franz Andermatten - “He is one of the best Guides. We had him over our new pass from Saas to Zermatt ... also alone over the Weiss Thor” (p. 210). Most valuable, though, of Jacomb’s annotations are his recollections of Alpine climbing experiences, notably his note on the ascent with Leslie Stephen of the Alleleinhorn in 1860 (p. 227-9).
