John Fergus O'Hea

John Fergus O'Hea (c. 1838 – 2 September 1922) was an Irish political cartoonist who sometimes published under the pseudonym Spex. Born in Cork, he was the son of James O'Hea, a barrister who was active in the Young Ireland movement and had been secretary to Daniel O'Connell. He attended the Cork School of Design, and painted trade union banners for Cork parades in the 1860s, 70s and 80s.

As a cartoonist, his early work appeared in the Dublin Weekly News, a nationalist newspaper, in the late 1860s. In 1870 he co-founded the humorous magazine Zozimus, an Irish answer to Punch, with journalist Alexander Martin Sullivan. O'Hea was chief artist and drew the covers. In its second year Richard Dowling became editor. Other cartoonists who contributed included Harry Furniss and Wallis Mackay. O'Hea also drew cartoons for the European Civiliser in the early 1870s. In 1872, after Zozimus folded, he moved to London and contributed to an Irish-run magazine called Tomahawk, which only lasted a few issues.

Back in Dublin in 1874, O'Hea, Dowling and Edwin Hamilton founded Ireland's Eye. After the style of Vanity Fair, each issue featured a colour caricature of a notable person, drawn by O'Hea under the name "Spex". Two editions of each issue were published, one at 6d with the cartoon in colour, the other at 3d with the cartoon in black and white. Ireland's Eye closed in 1876, after which O'Hea and Hamilton revived Zozimus as Zoz. O'Hea drew a full or double page cartoon in each issue until it too folded two years later. In 1879 O'Hea and Hamilton launched a new magazine, Pat, which ran until 1883 and also featured cartoons by Thomas Fitzpatrick.

For a time O'Hea was manager of the pictorial department of the Evening Telegraph. He lived in London from the 1893 until his death. Towards the end of his career, in 1914–15, he drew cartoons for Thomas Fitzpatrick's magazine The Lepracaun, during Fitzpatrick's final illness.
