The First Virtual Meeting Was in 1916

> Due to limited seating in New York and Philadelphia, members were allowed only a single admission ticket, and ladies were explicitly not invited. (Boo.)

We get it, different times had different morals and ethics. But I'm sure the author would have been above all that if they were around in those times.

The whole article is very explicit about looking at the past through the lenses of today, and it is written in a informal style. The 'Boo' fits right in, and I don't understand why it somehow triggered a response. It would be pretty weird if they mentioned to 'no girls allowed' without any commentary.
