Ustad Ahmad Lahori

Ustad Ahmad Lahori, also called Ahmad Mi'mar, Ahmad the Architect (c. 1570–1649), was a Persian-speaking architect and engineer serving the Mughal emperor Shah Jahan. The emperor's official chronicle names him with Ustad Hamid among the planners of the Red Fort at Delhi, built from 1639 to 1648 as the centre of the new capital Shahjahanabad.

Ahmad is widely credited with designing the Taj Mahal at Agra, the marble mausoleum for Shah Jahan's wife, though the only explicit evidence is a poem by his son Lutfullah Muhandis. His three sons also became architects. Ahmad died in 1649.
