Seventy years of computer history in about Twenty minutes

With nothing but a box-full of actual see-and-touch artifacts from the last hundred years, we will meet the first person to invent the concept of a computer program, and the person to discover the first real computer "bug" and invent the concept of a computer language (they were both women). We will discover why Samuel Morse's telegraph still lives in the newest "smart" devices, how Golden Age movie actress Hedy Lamarr helped make cellphones possible, and how "It's all just ones and zeroes" changed everything.
