Jac P Thijsse

Today is the anniversary of the death of the Dutch conservationist and botanist Jac P Thijsse. Jac founded the Society for the Preservation of Nature Monuments in Holland. His 60th birthday present was a wildlife garden in Bloemendaal near Haarlem.
After WWI, a Dutch food company by the name of Verkade (vare-Kah-dah) ask Jac to create some album books on the Flora of the Netherlands. Essentially, the books became a collector series Album with empty spots for photo cards, which were distributed individually with the biscuits. The Dutch would buy their biscuits, and then they would place the card in the space designed for it in the book. These albums were quite trendy among the Dutch and today sell for hundreds to thousands of dollars apiece today on auction websites.
Today in the Netherlands, there is a college named after Jac, and he always makes the top 100 Dutchman's list.
