I would hazard a guess – for those in Ireland and the UK at any rate – that there’s hardly a man, woman or child who has not, at some time, been touched by the life’s work of one John Clarke. Certainly, if you’ve ever savoured a bag of fat, golden, creamy-on-the-inside, vinegared-on-the-outside chip-shop chips, what you’ve eaten owes a certain debt to this unassuming man of Antrim.

To say that Mr. Clarke (1889-1980) was a potato breeder of note is somewhat of a understatement. Though he left school at the age of 12 and had no formal scientific or horticultural training, he was responsible for the development of 33 certified varieties of potato, most of which bear the prefix Ulster, and some of which were subsequently cross-bred to produce varieties very familiar to us: Maris Piper, long the potato of choice for the chipper, is a second generation (or F2) descendant of a John Clarke variety, Ulster Knight, and most of you will have eaten Maris Pipers, even if, at the time, their name was a mite less important than their role as a welcome source of soakage.
