Dutch elm disease (DED) is caused by a member of the sac fungi (Ascomycota) affecting elm trees, and is spread by the elm bark beetle. Although believed to be originally native to Asia, the disease has been accidentally introduced into America and Europe, where it has devastated native populations of elms which had not had the opportunity to evolve resistance to the disease. The name "Dutch elm disease" refers to its identification in 1921 and later in the Netherlands by Dutch phytopathologists Bea Schwarz and Christine Buisman who both worked with Professor Westerdijk. The disease is not specific to the Dutch elm hybrid.

“Too nice is neighbor’s fool.”
—Common Dutch saying, trans by Johanna C. Prins.
“I want to celebrate these elms which have been spared by the plague, these survivors of a once flourishing tribe commemorated by all the Elm Streets in America. But to celebrate them is to be silent about the people who sit and sleep underneath them, the homeless poor who are hauled away by the city like trash, except it has no place to dump them. To speak of one thing is to suppress another.”
—Lisel Mueller (b. 1924)
“Narcissist: psychoanalytic term for the person who loves himself more than his analyst; considered to be the manifestation of a dire mental disease whose successful treatment depends on the patient learning to love the analyst more and himself less.”
—Thomas Szasz (b. 1920)
