Lennox Allen was a member of a prestigious Louisville family that made its mark in the local arts community. He studied with fellow Louisville artist Ann Troutman and was a member of the Arts Club of Louisville and several national arts associations. He exhibited throughout the latter half of the 20th century.

Allen maintained a winter studio in a carriage house off St. James Court in Old Louisville and a summer studio at Rockport, Massachusetts. He painted landscapes from the American West to Northern Europe. He loved to capture images from his Glenview neighborhood, the creeks and marinas, on the Ohio River.

He once told a newspaper reporter that he was “dead down on modern painting…. The thing in painting is to give people something they want to look at or that reminds them of something they have seen in life.”
