Significant discovery

In the 1920s, Hedwig and her colleagues, Esther Applin and Alva Ellisor, were given macrofossil samples by their company to study. These samples were too damaged to be considered useful in macrofossil study, but the microfossils were almost entirely intact. The most well-maintained of these specimens were the foraminifera. However, the majority of micropaleontologists at the time did not believe that the single-celled organisms were diverse enough to have any practical applications and had therefore been ignored. Together, the women discovered that the species actually provided very detailed stratigraphic correlations and were incredibly useful in their field. Over the years this discovery was claimed by the men who had dismissed them and has been attributed to several different men since.


Legacy

Upon her death in 1985, Kniker’s estate funded the addition of 39 bells to the University of Texas’

. Following the completion of the project in 1987, the building was renamed the Kniker Carillon, in her honour. The carillon celebrates Kniker as one of the first female graduates in geology from the University of Texas. A portion of the specimens that Kniker collected throughout her lifetime are contained within the Non-vertebrate Paleontology Laboratory’s Type Collection at the Jackson School Museum of Earth History, a division of the University of Texas.
