Felix Christian Klein (German: [klaɪn]; 25 April 1849 – 22 June 1925) was a German mathematician and mathematics educator, known for his work in group theory, complex analysis, non-Euclidean geometry, and the associations between geometry and group theory. His 1872 Erlangen program classified geometries by their basic symmetry groups and was an influential synthesis of much of the mathematics of the time.
During his tenure at the University of Göttingen, Klein was able to turn it into a center for mathematical and scientific research through the establishment of new lectures, professorships, and institutes. His seminars covered most areas of mathematics then known as well as their applications. Klein also devoted considerable time to mathematical instruction, and promoted mathematics education reform at all grade levels in Germany and abroad. He became the first president of the International Commission on Mathematical Instruction in 1908 at the Fourth International Congress of Mathematicians in Rome.

Theodor Albrecht Edwin Klebs (6 February 1834 – 23 October 1913) was a German-Swiss microbiologist. He is mainly known for his work on infectious diseases. His works paved the way for the beginning of modern bacteriology, and inspired Louis Pasteur and Robert Koch. He was the first to identify a bacterium that causes diphtheria, which was called Klebs–Loeffler bacterium (now Corynebacterium diphtheriae). He was the father of physician Arnold Klebs.

Count Wilhelm Otto Albrecht von Bismarck-Schönhausen (1 August 1852 – 30 May 1901) was a German counselor, civil servant and politician, who served as a member of the Reichstag from 1880 to 1881 and president of the Regency of Hanover from 1889 to 1890. The youngest son of Otto von Bismarck, he and his brother Herbert von Bismarck both resigned their posts after the elder Bismarck was dismissed as Chancellor of Germany in 1890. Wilhelm subsequently accepted an appointment as Governor of East Prussia in 1894. Mount Wilhelm (German: Wilhelmsberg, or in Kuman: Enduwa Kombuglu, or Kombugl'o Dimbin) the highest mountain in Papua New Guinea at 4,509 metres (14,793 ft), part of the Bismarck Range, was named after him by Hugo Zöller.
