Welcome to the Porter House Museum!
Home of A.F. Porter, Naturalist
Decorah, Iowa
Located in the former Decorah home of Adelbert Field Porter (1879 – 1968) and Grace Young Porter (1880 – 1964), the Porter House Museum is an inspiring exploration of history, nature, and art.  

“Bert” (as he was more commonly called) was a gentleman naturalist, collector, and photographer who traveled throughout the world in pursuit of butterflies, rocks, and other curiosities.  A man of artistic sensibilities, Bert used his nature collections to create unique “nature art,” for which he became well known during his lifetime. 
At the museum, visitors experience the historic travels, art, and collecting of this naturalist and his wife against the backdrop of Victorian elegance that was their home and heritage.
