Lancelot Hogben

Lancelot Thomas Hogben FRS FRSE (9 decembre 1895 – 22 augusto 1975) esseva un zoologo experimental e statistician medical britanno. Ille ha devenite cognoscite pro su uso del rana africane con unghias (Xenopus laevis) como organismo modello pro recerca biologic in le initio de su carriera, pro su opposition al movimento de eugenica in le medietate de su vita, e pro scriber libros popular super scientia, mathematica e lingua in su ultime annos.

 Vita initial e education 
Hogben nasceva e cresceva in Southsea prope Portsmouth in Hampshire. Su parentes esseva methodistas. Ille frequentava le Tottenham County School in London, post que su familia se moveva a Stoke Newington, ubi su matre habeva crescite. In 1907, ille comenciava studiar physiologia como studente de medicina in Trinity College, Cambridge. Ante poter acceder a Cambridge, ille se matriculava in le Universitate de London como studente externe, e obteneva su diploma de Bachelor in Scientia (BSc) in 1914. Ille completava su studio in Cambridge in 1915 con un grado ordinari de BA.

Durante iste tempore, ille adoptava convictiones socialiste e cambiava le nomine del Fabian Society del universitate a Socialist Society, deveniente un membro active del Independent Labour Party. Plus tarde in su vita, ille prefereva describer se como “un humanista scientific”.

Durante le Prime Guerra Mundial, ille esseva pacifista e se univa al Quakers. Ille laborava durante sex menses con le Croce Rubie in Francia, sub le auspicio del Friends' War Victims Relief Service e le Friends' Ambulance Unit. Ille retornava al Anglaterra e esseva incarcerate in Wormwood Scrubs como objector de conscientia in 1916. Su sanitate collabava e ille esseva liberate in 1917. Su fratre George esseva etiam un objector de conscientia, serviente con le Friends' Ambulance Unit.

 Carriera 
Post un anno de convalescentia, Hogben acceptava positiones como lector in universitates de London, e in 1921 obteneva le titulo de Doctor in Scientia (D.Sc.) in zoologia del Universitate de London. In 1922, ille se transferiva al Universitate de Edinburgh, in le Departmento de Recerca in Reproduction Animal.

In 1923, Hogben esseva un del fundatores del Societate pro Biologia Experimental e de su publication, le British Journal of Experimental Biology (plus tarde renominate Journal of Experimental Biology in 1930), insimul con Julian Huxley e le geneticista Francis Albert Eley Crew. Secundo Gary Werskey, Hogben esseva le sol fundador qui non manteneva ideas eugenic. In le mesme anno, ille esseva eligite Fellow del Royal Society of Edinburgh. Ille recipeva le Premio Keith del Societate pro le periodo 1933–1935. Postea ille acceptava un position in le Universitate McGill in Canada.

In 1927, ille deveniva professor de zoologia al Universitate de Cape Town in Africa del Sud. Illac, ille laborava in endocrinologia, studiando le proprietates del camaleon del rana Xenopus. Il constatava que le color del rana adulte dependeva de su ambiente initial: ranas silvestre deveniva brun-verde, ranas allevate in obscuritate deveniva nigre, e illas in lumine deveniva clar. Hogben theorisava que iste capacitate de cambiar color esseva ligate al glandula pituitari. Post remover le glandula, le ranas deveniva blanc, independentemente de su ambiente.

Hogben tamben constatava un effecto secundari post iste removal, que ille tentava compensar per injectiones de extracto pituitari ab bove. Ille observava que feminas de Xenopus ovulava intra pocas horas post le injection. Assi, Hogben per hasardia discoperiva un methodo pro testar le graviditate human. Ille comprendeva que le extracto bovin resembleva chimicamente le hormone chorionic human (HCG), producite per feminas gravide. Il confirmava que feminas de Xenopus, injectate con urina de feminas gravide, ovulava intra horas.

Malgrado le attrahentia del position in Africa del Sud, Hogben quitava le pais a causa de su opposition al politicas racial.

In 1930, ille retornava al Britannia, acceptante un catedra in Biologia Social al London School of Economics. Illac, ille continuava le disveloppamento del Test de graviditate de Hogben. Le testes anterior pro graviditate prendeva plure dies e requireva le morte de micios o cuniculos. Le methodo de Hogben prendeva solmente horas e non occideva le ranas, que poteva esser reusate. Su methodo deveniva le standard international pro testes de graviditate durante circa quindec annos, ab le medietate del annos 1930 usque al annos 1940.

Le position in Biologia Social esseva supportate per le Rockefeller Foundation. Quando le fondation cessava su supporto, Hogben se transferiva al Universitate de Aberdeen in 1937 como Professor Regius de Historia Natural.

Durante le Secunde Guerra Mundial, ille habeva responsabilitate pro le statistica medical del armea britannic. Ab 1941 usque 1947, ille esseva Professor Mason de Zoologia al Universitate de Birmingham, e postea Professor de Statistica Medical ibi usque 1961, quando ille se retirava. In 1963, ille deveniva le prime Vice-Chancellor del Universitate de Guyana, ma ille resignava in 1965.
