ST. LOUIS.- The Sheldon Art Galleries presents the exhibit Ars Botanica: Works by Leslie J. Laskey starting on September 30, 2006 and running through January 27, 2007. Master artist and Professor Emeritus of Architecture at Washington University in St. Louis, Leslie Laskey has, among many other formal themes, investigated the aesthetic possibilities of flora for over 50 years. The exhibition Ars Botanica presents a range of works by the artist in many media in a mini-retrospective of styles and approaches to the subject. Laskey's explorations encompass the abstraction form to simple positive and negative spaces, the effects of color relationships and an investigation of materials and textures – all tenets of the Bauhaus model – which Laskey surveyed as a student at the Institute of Design (now the Illinois Institute of Technology) with founder and former Bauhaus professor Lászlò Moholy-Nagy.
