A Ukrainian Jew, Haffkine found his early career obstructed by his refusal to convert to the Russian Orthodox Church. He emigrated and worked at the Pasteur Institute in Paris, where he developed an anti-cholera vaccine that he tried out successfully in India. He is recognized as the first microbiologist to develop and use vaccines against cholera and bubonic plague. He tested the vaccines on himself. The three items in good conditon, lightly aged. ONE: ALS. 2pp., 12mo. He has been 'away from town', but now hopes to send 'a note on my work' within the week. 'It wd. Be a help to me if you could kindly lend for my inspection either a former edition of the "Men of the Time," or a specimen proof of another, similar note'. TWO: ALS. 1p., 12mo. 25 July 1899. He has not been able to send 'the sketch in question', having again been out of town. 'I am leaving to morrow again for the day, but shall try to get the note ready on Thursday & let you have it on Friday as you mention.' THREE: ACS. 27 July 1899. 'I hope to be able to send you the biographical sketch promised during the day to-morrow, Friday'. Haffkine autographs do not often appear on the market.…

Both items in good condition, lightly aged, as is an enclosure to the second letter, a photocopy of Lowbury's pamphlet 'A Letter from Hampstead'. ONE: 24 September 1969. 2pp, 12mo. In envelope addressed to Fry at his East Dean home The Toft. He is grateful for Fry's letter praising his collection of poems 'Figures of Light'. He continues: 'Several people have asked me about the red light; I am half sorry now that I did not include a footnote to explain the obscure reference (though perhaps it gains in other ways by giving the reader a bit of a puzzle!) One friend asked me if I meant a hospital, a cinema, a brothel, a psychiatrist's house, - or Death? By a curious paradox (disturbing to me as a doctor!) I did have Death as well as the Doctor in mind when I wrote those lines.' He is considering rewriting the poem 'if it is to appear in print again', but is glad Fry 'liked it in spite of the obscurity'. He concludes on a personal tone, regarding his wife Alison and her brother and Lowbury's father-in-law 'Andrew', i.e. the Scottish poet Andrew Young (1885-1971), and a party at Yapton. TWO: 24 November 1987. 2pp, 12mo. He begins by explaining that he is sending Fry a copy of his 'little book, VARIATIONS ON ALDEBURGH, which the Mandeville Press brought out in April: it has some attractive drawings by Donald Fairhall'. (The book itself is not present.) He continues with reference to a book which was published by the Keepsake Press on the same day as the other, titled 'A Letter from Hampstead'. Both books have sold out, but he was sent the copy of the first by the publishers. He explains that he is sending Fry a photocopy of the second book (which is present here). He explains that it is 'the fourth in a series of "apocryphal letters", the others being by (supposedly by) historical characters', whom he names. He explains that the previous volume, regarding 'Queen Caroline Matilda of Denmark the youngest sister of George III, married to the mad King Christian vii [] is illustrated by John Bratby, with some rather nightmarish pictures!' He ends in anticipation of 'receiving the material for me to send to the actors, after we have discussed "casting", etc. for 15 December'.…

6 pp. on bifolium. 18 x 11.5 cm. An important and extensive letter to a high-ranking government official concerning the proposed relocation of the newly founded Institute for Serum Research and Serum Testing from Steglitz to Frankfurt am Main.The institute, established only earlier that year under the direction of Paul Ehrlich, was already being considered for transfer to Frankfurt. Koch, asked to provide an expert opinion on the matter, responds with notable frankness and scientific caution. Reflecting on the uncertain future of serum therapy and immunological research, he writes: "Augenblicklich weiß Niemand, welchen weiteren Entwicklungsgang die Serumforschung und damit die Serumkontrole nehmen wird" ("At present nobody knows what further course serum research, and with it serum control, will take"). He continues with striking scepticism regarding the exaggerated expectations initially attached to serum therapy: "Die kühnen Hoffnungen welche anfangs gehegt wurden, sind bisher nicht in Erfüllung gegangen" ("The bold hopes initially entertained have thus far not been fulfilled"). Although Koch expresses the wish that his pessimistic assessment might prove mistaken, he nevertheless believes that substantial progress would require many years.For this reason, he considers it unwise to disturb the institute so soon after its establishment in Steglitz: "Unter diesen Umständen halte ich es für bedenklich, das Institut [.] nachdem es sich kaum in Steeglitz eingerichtet hat, schon wieder durch eine Verlagerung zu beunruhigen" ("Under these circumstances I consider it questionable to unsettle the institute again by relocation after it has scarcely established itself in Steglitz"). Koch further questions the practical and administrative rationale of integrating such an institute into a municipal health authority and argues that Frankfurt, wealthy enough in its own right, could easily found an independent biological institute without relying indirectly upon a state-controlled serum station.While encouraging the establishment of broader biological and immunological research facilities, Koch insists that "die staatliche Kontrolstation sollte man dabei ganz aus dem Spiele lassen" ("the state control station should be left entirely out of the matter").Three years later, despite Koch's reservations, the institute was indeed transferred to Frankfurt under Ehrlich's continued leadership as the Royal Institute for Experimental Therapy. A highly significant scientific and institutional document, revealing Koch's cautious and pragmatic attitude toward the rapidly developing field of immunology and illustrating contemporary debates surrounding the organization of biomedical research in Imperial Germany. - Small tear along fold.

4 pp. on bifolium. 20 x 12 cm. An exceptional and highly informative letter to Koch's favourite pupil, the bacteriologist Georg Theodor August Gaffky (18501918), concerning his expedition and research into African sleeping sickness (trypanosomiasis).Koch reports from the midst of his travels through German East Africa, where he was investigating outbreaks of the disease: "Ich bin immer noch auf der Wanderung und auf der Suche nach der Schlafkrankheit" ("I am still travelling about and searching for sleeping sickness"). Upon receiving news that the epidemic had broken out in the Muansa district, he had hoped to direct the expedition there immediately, but numerous difficulties concerning transport and travel arrangements delayed the journey.The letter contains vivid and extensive descriptions of the hardships of travel as well as the striking beauty of the African landscape. Koch evokes the scenery surrounding his residence with remarkable sensitivity to light and atmosphere: "Dann kommt der See . mit Felseninseln hineingestreut. Alles in ganz weichen, bläulichen Farben, die fortwährend mit dem Stande der Sonne wechseln, so daß man fortwährend neue Eindrücke hat" ("Then comes the lake . scattered with rocky islands. Everything in very soft bluish colours, constantly changing with the position of the sun, so that one is continually receiving new impressions"). Yet he immediately contrasts this beauty with the omnipresence of disease: "Aber wie so oft in den Tropen, unter der schönen Decke schlummert das Verderben" ("But as so often in the tropics, beneath the beautiful surface destruction lies dormant").Koch describes seeing disease and pathogens everywhere in the water, huts, walls, and crevices but notes with frustration that the very illness he had hoped to study was absent: "Und in diesem Orte, wo es von tropischen Krankheiten wimmelt, fehlt gerade die, auf welche ich meine Hoffnungen gesetzt hatte, die Schlafkrankheit" ("And in this place, teeming with tropical diseases, precisely the one on which I had pinned my hopes, sleeping sickness, is lacking"). Thousands of inhabitants had been examined, and Koch himself had spent days travelling across the lake in a small pinnace, all in vain. The reports of an outbreak ultimately proved mistaken "zum Glück für die Kolonie" ("fortunately for the colony") forcing the expedition onward to Entebbe, "the actual centre of the sleeping sickness regions".The letter closes on a more optimistic note, with Koch expressing satisfaction over the founding of a microbiological association with numerous members and asking Gaffky to convey his greetings to the gentlemen involved.A remarkable scientific and historical document, combining first-hand observations of tropical medicine, colonial East Africa, and expeditionary hardship with unusually vivid landscape descriptions by one of the founders of modern bacteriology.

4to. 3 pp. on 3 ff. In French, the preface to a book by Dr. Paul Held on the physician Guy-Crescent Fagon. Nicolle appreciates in this book the style, the precision, and the impression of authenticity that emanates from the portrait of Fagon, a botanist who became Louis XIV's "doctor", "more hygienist than therapist. It is this mistrustful prudence, this wisdom that dictated, no doubt, the clear advice he gave to the beautiful Madelonne, insipid pecorist, and to Bayle, the old loner. I understand that the same qualities advised him to wait for the progress of the royal gangrene and that he judged it useless to add medical poisoning to the criminal poisonings he discovered at Court" (transl.). - Provenance: Sale of the collection of Dr. Villard (8 March, 2001, lot 250).…
