The unit of study is the unfolding organism, and the timeline upon which embryology is focused is brief compared to the life cycle of the organism. Developmental biology is the science of studying development, which includes all of the processes that are required go from a single celled embryo to an adult. While embryos undergo development, so to do later stages of organisms. -

Wilhelm Roux (1850 - 1924) – Seine Hallesche Zeit
Aus dem Institut für Anatomie und Zellbiologie an der Martin-Luther-Universität Halle-Wittenberg (Direktor: Univ.-Prof. Dr. med. Dr. agr. Bernd Fischer) Wilhelm Roux (1850 - 1924) – seine hallesche Zeit Dissertation zur Erlangung des akademischen Grades Doktor der Zahnmedizin (Dr. med. dent.) vorgelegt der Medizinischen Fakultät der Martin-Luther-Universität Halle-Wittenberg von Ulrike Feicht geboren am 19.12.1973 in Halle/S.

Jahrhunderts in Wissenschafts-Kreisen eine Berühmtheit. Sein Wechsel nach Halle läutete eine neue Ära am Anatomischen Institut in Halle ein. Hatten all seine Vorgänger diese Einrichtung geprägt, so konnte Roux durch die lange Zeit seines Wirkens deutliche Zeichen setzen. Da er die übliche Unterrichtsmethodik für nicht effektiv hielt, bemühte er sich Zeit seines Lebens um bessere Lernbedingungen für die Studenten. Unermüdlich engagierte er sich für die Neugestaltung und Verbesserung des anatomischen Unterrichtes. Ebenso suchte er nach fähigen Mitarbeitern, die auf dem Gebiet der Entwicklungsmechanik und der kausalen Forschung mit ihm arbeiten und forschen sollten. Die Forderungen an seine Mitarbeiter waren hoch. Er stellte nicht nur an sie Forderungen, sondern unterstützte ihre Karrieren und bot Hilfe bei privaten Problemen an. Die „Wilhelm-Roux-Sammlung“ war anfangs im Anatomischen Institut untergebracht und ist heute nur noch in einzelnen wenigen Fragmenten erhalten. Ebenso konnte die „Wilhelm-Roux- Stiftung“ nicht über einen längeren Zeitraum hinaus am Leben erhalten werden. -
The Emergence of Life and Form!
The Emergence of Life and Form! Living in the 21st century as we gingerly grind towards a future of genetically engineered humans, it is perhaps a good time to mull over the journey of our quest to understand the beginning of new life. From ancient Arabs and old Germans postulating that mothers alone were responsible for the origin of newborns to ancient Greeks placing the 1 burden of origin on fathers , indeed, humanity’s interest in early embryonic development is of immense antiquity. Hippocrates (460-380 BC), the ancient physician, 3,4 imagined that a mother’s breath had the power to endow form ! In the early years of Scientific Revolution, the smartest men and women of the day grappled with the big questions of the origin of new life. In the absence of tools for a systematic enquiry, early philosophical debates seeking to explain the emergence of organic forms gave rise to two intensely contended ideas - Preformationism and Epigenesis, that applied to all organisms - plants and animals. Figure 1: Preformationism- this image is called ‘origin of man’ and has been adapted from the original woodcut by the Dutch anatomist Thomas Kerckring. It was first published in ‘A ground-plan of the origin of man’ (Anthropogeniae ichnographia) in 1671. Within the figure itself Fig I shows ‘two humane eggs of different bigness’, fig II ‘an Embryo of three, or at the most four days after Conception’, and fig III ‘the Hepar uterynum [placenta] with the Veins and Arteries … dispersed through the substance of it’. Fig IV ‘represents to the eye a gristly Skeleton of an embryo of three weeks’, fig V ‘an Embryo of one month’, and fig VI, to the modern eye the diminutive skeleton of a child, ‘an Embryo of six weeks’. -
Visual Standards and Disciplinary Change (Journal Article)
Hist. Sci., xliii (2005) VISUAL STANDARDS AND DISCIPLINARY CHANGE: NORMAL PLATES, TABLES AND STAGES IN EMBRYOLOGY Nick Hopwood University of Cambridge When I worked in developmental biology between 1986 and 1991 only two books had permanent places on my bench. The first, ‘Maniatis’, was a manual of the molecular cloning methods that our Cambridge laboratory was using to identify genes that specify muscle development in the South African clawed frog, Xenopus laevis. The second was ‘Nieuwkoop and Faber’, a ‘normal table’ that describes Xenopus embryos, one of the half-dozen model systems on which most developmental biol- ogy has been done. I knew the ring-bound recipes of Tom Maniatis et al. inside out, but with its dense morphological descriptions Pieter Nieuwkoop and Job Faber’s Systematical and chronological survey of the development from the fertilized egg till the end of metamorphosis seemed an alien work from a bygone age — it was first published in 1956 — and I read only those few of the 250 pages that give ‘external and internal stage criteria’ through early development. My attention focused instead on the fold-out plates, a series of stippled line drawings that I photocopied and stuck above the bench. By internalizing these images, first encountered in an undergradu- ate practical class, I learned to tell gastrulae from blastulae and neurulae, and then stage 10 ½ early gastrulae from stage 11 mid-gastrulae, and so to see my frogspawn develop in the same way as other people saw theirs. “Embryos”, the Methods sec- tions of our papers reported, “were staged according to Nieuwkoop and Faber”. -
Hans Spemann (1869-1941) [1]
Published on The Embryo Project Encyclopedia (https://embryo.asu.edu) Hans Spemann (1869-1941) [1] By: Wellner, Karen Keywords: Biography [2] Organizers [3] Transplantation [4] Hans Spemann [5] was an experimental embryologist best known for his transplantation studies [6] and as the originator of the “organizer” concept. One of his earliest experiments involved constricting the blastomeres of a fertilized salamander [7] egg [8] with a noose of fine baby hair, resulting in a partially double embryo with two heads and one tail. Spemann continued changing variables such as the amount of time the embryo was constricted and the degree of constriction, all of which added more empirical evidence to Hans Driesch’s studies showing that embryonic cells could self-regulate to varying degrees. Spemann’s long list of “simple” experiments and significant findings were mainly carried out at his laboratory, the Spemann School [9] at the University of Freiburg [10], Germany, where numerous graduate students collaborated with Spemann to investigate embryonic induction [11]. Spemann was born 27 June 1869 in Stuttgart, Germany to Lisinka and Wilhelm Spemann [12], a publisher. From 1878 to 1888 he attended the Eberhard-Ludwig School at Stuttgart. After one year of business with his father and a year in the military, Spemann decided to study medicine at the University of Heidelberg [13]. Influenced by the works of Johann Goethe, Ernst Haeckel [14], and Carl Gegenbaur [15], Spemann studied embryology [16] along with clinical science. In 1892 Spemann married Klara Binder and soon after entered the University of Munich [17] for more clinical training. In studying with Gustaf Wolff [18] and Gegenbaur, Spemann’s life-long interest in zoology took hold. -

Title of Thes l s/Project/Extended Essay I Author: csl&t"r;;; (date) ABSTRACT Traditionally, the achievements of Hans Driesch (1867-1941) in the field of experimental embryology have been dissociated from his philosophy of vitalism. His vitalism has been judged to have been a result of his inab ility to explain certain experimental results in conventional mechanistic terms Further, the fact that Driesch eventually left his career in biology to become a professor of philosophy has been taken as proof of the assumption that a philosophy of vitalism is incompatible with the practice of experimental science. -
