Christian Ludwig Gerling (1780–1858) was a notable German mathematician and astronomer. He is best known for his work in the field of astronomy and for his contributions to the development of astronomical instruments. Gerling was involved in the establishment of observatories and contributed to the study of celestial mechanics. In addition to his practical work, he made significant contributions to mathematical astronomy and helped advance the understanding of various celestial phenomena.

Christoph Heinrich Pfaff was a German physician and surgeon known for his contributions to medicine in the early 19th century. He is particularly noted for his work in ophthalmology and surgery. Pfaff was also involved in the academic and educational aspects of medicine, contributing to medical literature and the training of future medical professionals.

Eilhard Wiedemann (1876–1959) was a German physicist known for his contributions to the field of gas discharge physics and related areas. He is perhaps best recognized for his work on the properties of gases under electrical discharge and for his role in advancing the understanding of high-voltage engineering. Wiedemann is also associated with the Wiedemann-Franz law, which describes the relationship between electrical conductivity and thermal conductivity in metals.

Ernst Abbe (1840–1905) was a German physicist and optician renowned for his contributions to the field of optics and microscopy. He is best known for his work on the theory of optical imaging and for his inventions that improved the design of microscopes. Abbe formulated the Abbe sine condition, which provides guidelines for the design of high-performance optical systems.

Ernst Bessel Hagen is not a widely recognized term or individual in historical, scientific, or popular contexts as of my last knowledge update in October 2023. It could possibly refer to a lesser-known figure or be a combination of names or terms that may have relevance in specific fields or discussions that are not broadly documented. If you have more context or details about "Ernst Bessel Hagen," such as the field (e.g., science, literature, etc.
