Barbara Mcclintock's World
Barbara McClintock’s World Timeline adapted from Dolan DNA Learning Center exhibition 1902-1908 Barbara McClintock is born in Hartford, Connecticut, the third of four children of Sarah and Thomas Henry McClintock, a physician. She spends periods of her childhood in Massachusetts with her paternal aunt and uncle. Barbara at about age five. This prim and proper picture betrays the fact that she was, in fact, a self-reliant tomboy. Barbara’s individualism and self-sufficiency was apparent even in infancy. When Barbara was four months old, her parents changed her birth name, Eleanor, which they considered too delicate and feminine for such a rugged child. In grade school, Barbara persuaded her mother to have matching bloomers (shorts) made for her dresses – so she could more easily join her brother Tom in tree climbing, baseball, volleyball, My father tells me that at the and football. age of five I asked for a set of tools. He My mother used to did not get me the tools that you get for an adult; he put a pillow on the floor and give got me tools that would fit in my hands, and I didn’t me one toy and just leave me there. think they were adequate. Though I didn’t want to tell She said I didn’t cry, didn’t call for him that, they were not the tools I wanted. I wanted anything. real tools not tools for children. 1908-1918 McClintock’s family moves to Brooklyn in 1908, where she attends elementary and secondary school. In 1918, she graduates one semester early from Erasmus Hall High School in Brooklyn. -
Naturvidenskabernes Kanonisering. Forskere, Erkendelser Eller Kulturarv
NORDISK MUSEOLOGI 2006 G 2, S. 27-44 Naturvidenskabernes kanonisering. Forskere, erkendelser eller kulturarv KRISTIAN HVIDTFELT NIELSEN* Title: The ”canonisation” of the natural sciences. Abstract: This paper concerns recent official attempts to place science in Denmark within the context of a cultural canon. Based on differentiation between Mode 1 and 2 knowledge production, the paper points out that such attempts are highly contextualised and contingent on their different modes of application. Consequent- ly, they entangle scientific expertise with other social skills and qualifications. Like science museums and science centres, they are a means of dealing with science in the public agora, i.e. the public sphere in which negotiations, mediations, consulta- tions and contestations regarding science increasingly take place. Analysing the am- biguities and uncertainties associated with the recent official placing of science wit- hin an overall cultural canon for Denmark, this paper concludes that even though the agora embodies antagonistic forms of interaction, it might also lead the way to producing socially robust knowledge about science. Keywords: Cultural canon, science, Mode 1 and 2 knowledge production, Mode 2 society, agora, science museums, science centres. Naturvidenskab er ikke med i den officielle, denskabskanoner samt deres bredere betyd- danske kulturkanon, som blev sat i værk af ning for offentlighedens forståelse af naturvi- Kulturministeriet i 2005 (Kulturministeriet denskab, som jeg i denne artikel vil komme 2006).

Patrick H. Brown Department of Plant Sciences, University of California, Davis, CA 95616, US; E-mail: [email protected] The scientific discipline of plant nutrition is wonderfully broad in its scale and its scope. From the exploration of the function of nutrients as signals and regulators of plant function, to the role of plant nutrients in agricultural productivity and food quality, to the exploration of the effects of nutrient losses on global environments, plant nutrition is a truly integrative discipline and will play a critical role in mans’ ability to adapt to environmental change. -
John Burchenal Oral History Interview
Joseph Burchenal Interview, January 26, 2001 1 National Cancer Institute Oral History Interview Project Interview with Joseph Burchenal Conducted on January 26, 2001 by Peggy Dillon Darien, Connecticut PD: Good morning. This is Peggy Dillon of History Associates Incorporated. I am speaking with Dr. Joseph Burchenal for the NCI oral history interview series. We are at his home in Darien, Connecticut. Today is January 26, 2001. JB: Good morning. PD: I would like to talk with you today about your work in cancer chemotherapy in general and also your involvement with the National Cancer Institute in particular. Before we get into your career overall and NCI, I'd like to ask you about your background. If you could just tell me a little bit about your upbringing and education . I understand that you were interested in chemistry from a very early age. JB: I was born in Milford, Delaware, but I lived in Wilmington, Delaware, for the first part of my life. My mother died when I was three, in childbirth. So I lived with my father in Wilmington. He was a lawyer. I went to school at Tower Hill School. The majority of my friends in the school had fathers or mothers–fathers mainly–who worked for Dupont. They were very likely to, so that there was a lot of interest in chemistry there. In fact, it was the same way on the street where we lived, where the fathers were mostly chemists. But my interest in chemistry, I guess, started when I was eight years old and I had a cousin who was eleven who was given a Chemcraft set and he used to show us all of the interesting things that he could do with it. -

Glynn Harmon, Supervisor Julie Hallmark Billie Grace Herring James D. Legler Brooke E. Sheldon Discovery and Information Use Patterns of Nobel Laureates in Physiology or Medicine by Karen Suzanne Balcom, B.A., M.L.S. Dissertation Presented to the Faculty of the Graduate School of The University of Texas at Austin in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy The University of Texas at Austin August, 2005 Dedication I dedicate this dissertation to my first teachers: my father, George Sheldon Balcom, who passed away before this task was begun, and to my mother, Marian Dyer Balcom, who passed away before it was completed. I also dedicate it to my dissertation committee members: Drs. Billie Grace Herring, Brooke Sheldon, Julie Hallmark and to my supervisor, Dr. Glynn Harmon. They were all teachers, mentors, and friends who lifted me up when I was down. Acknowledgements I would first like to thank my committee: Julie Hallmark, Billie Grace Herring, Jim Legler, M.D., Brooke E. Sheldon, and Glynn Harmon for their encouragement, patience and support during the nine years that this investigation was a work in progress. I could not have had a better committee. They are my enduring friends and I hope I prove worthy of the faith they have always showed in me. I am grateful to Dr.
