Arthur Wolfe was born at Forenaughts House, near Naas, being the eighth of nine sons born to John Wolfe and his wife Mary, the only child and heiress of William Philpot, a successful merchant at Dublin. One of his brothers, Peter, was the High Sheriff of Kildare, and his first cousin Theobald was the father of the poet Charles Wolfe.
After the Irish Rebellion of 1798, Kilwarden became notable for twice issuing writs of habeas corpus on behalf of Wolfe Tone, then held in military custody, but these were ignored by the army and forestalled by Tone's suicide in prison. In 1795 he had also warned Tone and some of his associates to leave Ireland to avoid prosecution. Tone's godfather, Theobald Wolfe of Blackhall was Kilwarden's first cousin, and Tone may have been Theobald's natural son. These attempts to help a political opponent were unique at the time. After the passage of the Act of Union, which he supported, Kilwarden was created Viscount Kilwarden on 29 December 1800. In 1802, he was appointed Chancellor of the University of Dublin. Despite his actions on behalf of Wolfe Tone, Kilwarden was hated by the United Irishmen for his prosecution of William Orr in 1797, and he had entertained considerable fear for his safety after their failed rebellion. His murder in 1803 is often said to have been a delayed revenge for the death of Orr. Another theory is that it was a case of mistaken identity, the real target being his colleague Hugh Carleton, 1st Viscount Carleton. In 1802 he presided over the case against Major Sirr in which the habitual abuses of power used to suppress rebellion were exposed in court.
Father Gahan
In the same year he ordered that the well-known Catholic priest Father William Gahan be imprisoned for contempt of court. In a case over the disputed will of Gahan's friend John Butler, 12th Baron Dunboyne, the priest refused to answer certain questions on the ground that to do so would violate the seal of the confessional, despite a ruling that the common law did not recognize the seal of the confessional as a ground for refusing to give evidence. The judge may well have felt some personal sympathy for Gahan's predicament, as he was released from prison after only a few days.
Death
During the 1803 rebellion, Kilwarden, who had never been forgiven by the United Irishmen for the execution of William Orr, was clearly in great danger. On the night of 23 July 1803, the approach of the Kildare rebels induced him to leave his residence, Newlands House, in the suburbs of Dublin, with his daughter Elizabeth and his nephew, Rev. Richard Wolfe. Thinking that he would be safer among the crowd, he ordered his driver to proceed by way of Thomas Street in the city centre; however, the street was occupied by Robert Emmet's rebels. Unwisely, when challenged, he gave his name and office, and he was rapidly dragged from his carriage and stabbed repeatedly with pikes. His nephew was murdered in a similar fashion, while Elizabeth was allowed to escape to Dublin Castle, where she raised the alarm. When the rebels were suppressed, Kilwarden was found to be still living, and was carried to a watch-house, where he died shortly thereafter. His last words, spoken in reply to a soldier who called for the death of his murderers, were "Murder must be punished; but let no man suffer for my death, but on a fair trial, and by the laws of his country." He was succeeded by his eldest son John Wolfe, 2nd Viscount Kilwarden. Neither John nor his younger brother Arthur, who died in 1805, had male issue, and on John's death in 1830 the title became extinct.
