This sand is from the collection of the late Ivor Treby. It was collected from the shore of Lake Michigan near the Art Museum in 1990. It contains quartz, feldspar and biotite.
Ivor was a biochemistry teacher and poet with over 400 published poems. He considered himself to be a gay literary activist.
Ivor took early retirement in the 1980s and dedicated his time to researching two Victorian/Edwardian women poets who wrote under the pseudonym Michael Field. He also spent much of the next 20 years travelling abroad. Wherever he went he collected samples of sand and sediment.
