Joseph Summers (1843–1916) was a musician and composer.
He wrote a number of tunes[1] for Christian hymns, including "Palmyra", which is often associated with the hymn Thou art the everlasting word.[2][3]
There is an article here about one who appears to be a different Joseph Summers (1839-1917) whose biography is strangely similar to that of our Joseph Summers recorded at Praise.
