Inventions Week! Iowa's African Americans

In celebration of Black History Month in 2008, the State Library of Iowa compiled a document highlighting inventions from African Americans in Iowa.  "Black Inventors From Iowa"  includes available biographical information for the inventor and a description and diagram of the invention!  SEE a sketch of the can opener for which Albert Mendenhall, on May 9, 1916, received patent number 1,182,781.  THRILL to the 27 patents collected by David Nelson Crosthwait, Jr. (No diagrams for these.)  MARVEL at Walter G. Madison's elegant design for a flying machine! (Seen above)  It's so cool to get a taste of the ideas that make it all the way to the Big Time in Patent City.

Hey there! I just wanted to ask if you ever have any problems with hackers?
My last blog (wordpress) was hacked and I ended up losing several weeks
of hard work due to no back up. Do you have any methods to protect against hackers?

it looks fine however, when opening in I.E., it has some
overlapping issues. I merely wanted to provide you with a
quick heads up! Besides that, excellent blog!
