One of the presentations I found the most intriguing was the invention of the ballpoint pen. I use these pens every week, so it was interesting to see the information behind it and where it came from. Who would have ever thought that a pen could be a changing point in history! Students found it more efficient when doing school and work. The pen was created by John Loud, who was a Harvard Law alumni. He worked with leather. Because he worked with leather, he was constantly using pens to mark things, but he found that it wasn't efficient. This is why he created the ballpoint pen! Although John Loud created his design in 1888, the ballpoint pen didn’t become popular until years later, when Laszlo Biro improved upon it in the 1930s. The ballpoint pen is now a common tool in offices, schools, and homes, changing how we write and communicate. It is interesting to me how such a little tool can impact so much.
