I’m intrigued by recent messages concerning early electronic messages. Should anyone have examples of such messages and related software, I’d be delighted to consider them for the Smithsonian collections (complementing the materials elsewhere that Janet and others have used). Also, on the book and movie Hidden Figures, two recent blogs might be of interest: https://airandspace.si.edu/stories/editorial/hidden-figures-and-human-comput... http://americanhistory.si.edu/blog/hidden-figures.
