| step signal is generated.

| This is one of many conflicts between Elisha Gray and Alexander

| patent, one filing just hours before the other.
|
| What is also not as widely known is Bell also patented the
| autograph telegraph fax-like device.
|
| Read more at https://en.wikipedia.org/wiki/Elisha_Gray :
|
| " In April, 1875, ten months before the alleged theft of Gray's
| design, the U.S. Patent Office granted U.S. Patent 161,739 to
| Bell for a primitive fax machine, which he called the "autograph
| telegraph." The patent drawing includes liquid transmitters. "
|
| I'm sure there was no love lost between these two.

| What an adorable example of citogenesis:

| Refreshingly honest, really.

| Just fix the cite to an internal link. This doesn't need to be
| "adorable". It's literally a self-fixable bug that takes less
| time to fix than to make this comment.
|
| Always confuses me why people make "Behold! A problem!" posts
| when the problem itself is fixable in less text than that.

| brought to the telautograph page? Gp could just fix this on
| Wikipedia themselves...
