Frank Lloyd Wright was an architect, writer, philosopher and educator, who designed more than 1,000 projects, resulting in more than 500 completed works.
His work includes original and innovative examples of many different building types, including offices, churches, schools, skyscrapers, hotels and museums. He also often designed many of the interior elements of his buildings, such as the furniture and stained glass.
Wright authored 20 books and many articles and was a popular lecturer in the United States and Europe. His colorful personal life often made headlines, most notably for the 1914 fire at his studio at Taliesin in Spring Green, Wis.
His contributions to architecture in Indiana include houses in Ogden Dune, South Bend, Muncie, Fort Wayne and West Lafayette.
Already well-known during his lifetime, Wright was recognized in 1991 by the American Institute of Architects as "the greatest American architect of all time."
The public is invited to the event and to all monthly meetings the historical society has.
