Albert Myer regained his position as chief signal officer after the Civil War due to the reorganization of the Signal Corps, which was a decision influenced by high-ranking officials including President Andrew Johnson and General Ulysses S. Grant. Myer was officially restored to the role in 1866, with a permanent rank of colonel. He served as the chief signal officer until his death in 1880.

This reestablishment emphasized his crucial contributions during the Civil War and the value of his expertise in military communication. Here is an image of Albert Myer during his service:
