I need information on the process charles kettering went through to invent the electric cash register or the car self starter and did he have problems inventing them. I can only find out that he did invent them.
Here are some sites that will help you.
Thank you we already found these sights but the questions at school as by what process did he develop these inventions and what problems did he have. I cant find them on line or at the library.
This site, suggested by GuruBlue tells about Kettering's process in making these inventions.
His poor eyesight certainly counts as one of his problems. Check this site for more problems.
