Spinal cord compression. Spinal cord compression develops when the spinal cord is compressed by bone fragments from a vertebral fracture, a tumor, abscess, ruptured intervertebral disc or other lesion.
Early life. Samuel Finley Breese Morse was born in Charlestown, Massachusetts, on April 27, 1791. He was the first son of Jedidiah Morse, a clergyman, and Elizabeth Breese, of New Jersey.
Morse's first telegraph device, unveiled in 1837, did use a one-wire system, which produced an EKG-like line on tickertape. The dips in the line had to be de-coded into letters and numbers using a dictionary composed by Morse.
