 At his lunchtime talk for this conference, then-Harvard President Lawrence Summers had given three hypotheses for the higher proportion of men in high-end science and engineering positions, which were considered controversial by many.Reporters said they were told that no transcript of the talk existed, so Nelson suggested that they instead request a copy of the recording of the talk which had been made by President Summers accompanying undergraduate assistant.During Q&A after his talk, recognizing that the recording might be of interest, Nelson posed the first two questions, which alerted attendees that the talk had been recorded.
