James McCabe, the founder of the firm, was born in Belfast. He came to London in the 1770’s, settling at Royal Exchange in 1804. He became a Freeman of the Clockmakers Company in 1781 and a Warden in 1811, the year he died. He was succeeded by his son, also James, who is regarded as one of the finest English clock and watchmakers of the nineteenth century. He was apprenticed to Reid and Auld and gained admittance to the clockmakers Company in 1822. Robert Jeremy McCabe, James’s nephew, continued the business until he retired in 1883.
