History of Typography

After watching this video for the fourth time, I have learned the history of typography. Before watching this, I understood the basics of typography: Roman, Old Style, Transitional, and Modern. I must say that I was extremely rusty on the Sans Serif time period. I find it fascinating that Caslon's grandson was the created and instigator of sans serif fonts. I would really like to spend more time in the future studying sans serif fonts more thoroughly, for I feel I tend to stick to the more traditional and classic fonts.
