National Museums Scotland and Institute for the Study of Science, Technology and Innovation, the University of Edinburgh UNDERSTANDING TECHNOLOGY Public lecture Thursday 18 September 2008, 3:00 pm Professor David Bloor (Edinburgh University): “How Does an Aircraft Wing Work? British Physicists versus German Engineers: 1909-1926” Sustained and controlled powered flight was well established by about 1910, but the practical mastery of flight was not accompanied by a clear, theoretical understanding of how aeroplanes worked. For example, it was not clear how a wing produced lift. In the early years of aviation there were two very different theories under discussion. One was called theory of discontinuous flow, the other was called the theory of circulatory flow. The discontinuity theory was supported by British physicists; the circulatory theory was supported by German engineers. It turned out that the Germans were right and the British were wrong. The British fought a rearguard action argument against the correct explanation which lasted till the 1920s. Professor Bloor’s aim in the lecture is to describe the two theories, identify the people involved and explain the source of the British resistance.

PUBLIC LECTURE: September 25 JUDITH LEAVITT, University of Wisconsin “Make Room for Daddy: Men and Childbirth in Mid-Twentieth Century America.” This is the inaugural event in the Center’s series of Public Lectures in the History of Science, Technology and Medicine. See details and RSVP at http://www.pachs.net/events/archive/leavitt/

Time: 6:30 p.m. Location: The College of Physicians of Philadelphia

This program is free and open to the public. The lecture will be preceded by a reception, at 5:30 p.m.

Judith Leavitt examines how expectant fathers fared during hospital-based childbirth in the middle years of 20th-century America, ca. 1935-1985. Until very recently, historians describing the childbirth experience entirely neglected fathers-to-be. In the popular literature expectant fathers were caricatured and ridiculed as incompetent, ignorant fools pacing in the hallways and waiting rooms of hospitals. Leavitt argues that we cannot fully understand childbirth and its changes without adding fathers to the story and analysis. Her talk (and the forthcoming book upon which it relies) rescues fathers from childbirth history’s oblivion and reveals–not so surprisingly, but still insufficiently recognized–that these men, too, helped to shape childbirth events.

Leavitt will recount the stories of expectant fathers–many in the fathers’ and the mothers’ own voices. Her talk will remind listeners of their own experiences, and it will demonstrate that men’s childbirth stories are significant because fathers-to-be were active participants in changing hospital practices. At the same time as they tried to help their wives through their travails, these men increased available roles for themselves as they struggled to figure out their own preferences. Their accounts, whether humorous or serious, emotionally charged or ambivalent, show that men’s diverse responses to childbirth have mattered.
