Jackman, Isaac, was born about the middle of the 18th century, in Dublin, where he afterwards practised as an attorney. He ultimately removed to England, and for many years edited the Morning Post. He wrote some dramatic pieces. One, All the World's a Stage, is still occasionally acted. His other works have fallen into oblivion. 116
Jackson, William, Rev., born of an Irish family, possibly in England, in the middle of the i8th century. His father held a post in the Prerogative Court, Dublin. Early in life he maintained himself as a tutor in London, and afterwards, entering the Church, he became a popular preacher in Tavistock Chapel, Drury-lane. He was next chaplain to the Duchess of Kingston, on whose behalf he engaged in a controversy with Foote, the comedian. He went over to Paris on the business of the Duchess about 1790, and continued to reside there. Early in 1794 he came to Ireland on a secret mission to the leaders of the revolutionary party. Passing through London, he divulged his plans to an old friend John Cockayne, an attorney, who immediately entered into private communication with Pitt. In Dublin, Jackson and Cockayne had interviews with Tone, Rowan, and Lewins, relative to French assistance. Cockayne revealed everything that had passed to the Government, and on the 28th April 1794 Jackson was arrested on a charge of high treason, at Hyde's Coffee-house, in Palace-street, Dublin. He was tried a year afterwards, and upon Cockayne's evidence convicted. Brought up to receive sentence, 30th April 1795, he managed before entering the court to swallow a quantity of arsenic — in the hope, we are told, that in dying before conviction his little property might be preserved to his family. As he entered the dock he whispered to one of his counsel: "We have deceived the senate." The scene that ensued was one of the most dramatic enacted in those exciting times. His fortitude did not forsake him to the last; for it was scarcely perceived by the spectators that he was ill, when he fell down in the agonies of death, and after a few minutes' struggle died in the dock. In his pocket was found a paper with a few verses from the 25th Psalm, commencing: "Turn thee unto me and have mercy upon me; for I am desolate and afflicted." His remains were followed to St. Michan's (where his tombstone may now be seen) by an immense number of mourners. In Newgate before his trial he wrote a reply to Thomas Paine. A volume of his sermons was printed after his death. Cockayne was requited for the sacrifice of his old friend and client by a pension of £250. 331
Jacob, Arthur, Dr., an oculist, was born at Knockfin, Maryborough, 30th of June 1790. He studied medicine at Steevens' Hospital, Dublin, and subsequently at Edinburgh, Paris, and London. He settled in Dublin, where his high scientific attainments were soon acknowledged. In 1819 he discovered the membrane in the eye, afterwards called "membrana Jacobi." He was one of the founders of the Park-street School of Medicine, and of the City of Dublin Hospital. In 1838 he started the Dublin Medical Press. He died in September 1874, aged 84, having many years previously retired from practice. 233
Jacob, Joshua, the leader of an eccentric sect, generally known as "White Quakers," was born in Clonmel about 1805.
After a business career of great success as
a grocer in Nicholas-street, Dublin, about
1838 he was "disowned" by the Society
of Friends, of which he was a member,
on account of the extravagance of his
preaching and behaviour. He thereupon
gathered a few disciples, for the most
part members of the Society of Friends,
with whom he entered upon a career
of the wildest eccentricity. They dressed
in white, destroyed everything ornamental in their houses, and cherished innumerable scruples — professing all through
to keep to the spiritual sense of the Bible.
The society had its principal stations in
Dublin, Mountmellick, Clonmel, and Waterford. They issued a series of tracts entitled the Progress of Truth. Joshua Jacob
was imprisoned for two years for contempt
of court connected with trust property,
and while a prisoner fulminated anathemas against Lord-Chancellor Sugden and
Master Litton, as " Edward Sugden and
thy man Edward Litton." About 1849 he
gathered his followers into a communistic
society at Newlands, near Dublin, once
the residence of Lord Kilwarden. They
eschewed the use of meat, used bruised
corn alone as food, and accepted the fellowship of all comers. Joshua Jacob had early
put away his first wife without cause.
After her death he married a Catholic, a
woman of humble origin. The community at Newlands soon fell to pieces, and he returned to "the world," and entered into business at Celbridge. There
he reared a large family, all Catholics. The
