Thank you for that. It points out that the mysterious "young man" who drew attention to the issue was named Diane Hartley. An "addendum" to the story suggests that she is as much to credit for averting disaster as LeMessurier. It includes a footnote saying that "The sex-stereotyping of engineers and engineering is not found in all countries. I recall in particular a talented engineering student from Mauritius telling me that it was only when she came to the U.S. that she heard that engineering was a male field."
