The grove and the bosk played no real role in Daniel Urban Kiley's own pre-World War II professional landscape designs. But European military service – he was the principal designer of the main courtroom for the war trials in Nuremburg – brought him into contact with garden cultures new to him, garden cultures that included the work of André le Nôtre in France. A selection of landscapes illustrates Kiley's masterful use of the geometrically planned grove and demonstrates how, over time, the spaces within these groves became more complex and more engaging. Kiley's ability to modulate complexity had increased noticeably in his garden for Irwin and Xenia Miller, also in Columbus, a garden to accompany their modernist house designed by Eero Saarinen and first occupied in 1957. Here the planning and use of the grove became more involved and the spatial effects more varied, with the readings changing with viewpoint and promenade, and with the seasons of the year.
