The first patent

1at the end of 868, Edison came to Boston as a telegraph operator. In the same year, his first invention was patented, which is a device for automatically recording votes, namely "voting counter". Edison thought that this device would speed up the work of Congress and be popular, but a member of Congress told him that sometimes voting was slow because of political needs, so Edison decided not to create inventions that people no longer needed.
