The Sestercentennial of Alexander von Humboldt

For all nature lovers, natural philosophers, and curious minds who want to know why hundreds of thousands from around the world celebrated the centennial of Alexander von Humboldt’s birth on September 14, 1869, from Adelaide to Argentina, from San Francisco to St. Petersburg, with 8000 people pouring out into the streets in Cleveland, Ohio!

We  hope many of you will come to the Secrest Center and the Arboretum grounds for a day of science and the senses. From the aromas of Secrest flowers to the flavors of Ohio produce, from the biological, geophysical and political sciences of climate change, to the sights of Secrest plantings and natural areas and the sounds of seasonal songbirds. There is no cost for the program; bring your own picnic lunch but we will provide morning and afternoon refreshments.
