Honeyman and Keppie were a major architects firm based in Glasgow, created by John Honeyman and John Keppie in 1888 following the death of James Sellars in whose architectural practice Keppie had worked. Their most famous employee was Charles Rennie MacKintosh who started as a draughtsman in April 1889 and rose to partner level. The creation of the new Honeyman, Keppie and Mackintosh spelt the next phase in the evolution of the practice which as Honeyman and Keppie existed from 1888 to 1901.
Whilst often viewed independently, Mackintosh did much of his most famous work while employed in the firm. Other notable employees include James Herbert MacNair who began as an apprentice in the firm in 1894.
