The rescue was in the roots.

Sometimes the most useful part of a plant is the part you cannot see. George Husmann, a German immigrant associated with Hermann, helped develop Missouri grape growing and contributed to the international response to phylloxera, the insect devastating French vineyards in the nineteenth century. [1]

The State Historical Society of Missouri describes cooperation among Husmann, state entomologist Charles Valentine Riley, and fellow grower Herman Jaeger. Their investigations helped support the use of American vines and the grafting of European vines onto American roots. The response depended on shared observation and experimentation across the Atlantic. [1]

Husmann’s career also passed through the University of Missouri, where he taught fruit cultivation and forestry, before he moved to California in 1881. It is a reminder that Missouri’s German heritage includes laboratories in the broadest sense: farms, nurseries, notebooks, and the practical work of figuring out why a plant thrives. [1]

Imagine trying to solve a problem by changing only what you can see above ground. The grafting story suggests a different question: what is supporting the visible part? That is a useful way to approach history, too. A familiar landscape may depend on experiments and exchanges that leave very little obvious trace.
