"Medieval geometers" typically refers to mathematicians and scholars during the Middle Ages who contributed to the field of geometry, building on the foundations established by ancient Greek mathematicians like Euclid, Archimedes, and others. The medieval period, roughly spanning from the 5th to the late 15th centuries, saw a mix of continued study in geometry as well as the transmission of knowledge from the Islamic Golden Age.

Ferroelectric materials are a class of dielectric materials that exhibit a spontaneous electric polarization that can be reversed by the application of an external electric field. This polarization occurs even in the absence of an external electric field, meaning that ferroelectric materials have a non-centrosymmetric crystal structure, allowing for the alignment of electric dipoles within the material.

Arthur Moritz Schoenflies (1853–1928) was a German mathematician known for his contributions to geometry and crystallography. He is particularly recognized for the Schoenflies notation, which is a system used to describe the symmetry of geometric figures and molecular structures. This notation is part of his work in the study of symmetry operations and their applications in various fields, including physics and chemistry.

August Adler may refer to several different subjects, but without more specific context, it's difficult to determine exactly what you are asking about. There may be people, characters, or topics in literature, history, or current events associated with the name "August Adler.

Carl Anton Bretschneider (1813–1888) was a notable German botanist known for his contributions to plant taxonomy and botany. He is particularly recognized for his work on the flora of Central Europe. Bretschneider played a significant role in the study and classification of various plant species and is remembered for his meticulous research in the field.

David Gabai is a prominent American mathematician known for his contributions to the fields of topology and geometric topology. He has made significant advancements in understanding 3-manifolds, particularly through his work on the theory of hyperbolic manifolds and knot theory. Gabai is a professor at Princeton University and has received several prestigious awards for his research, including a MacArthur Fellowship. His work has helped to deepen the understanding of complex mathematical structures and has influenced various areas in mathematics.

Diane Maclagan is a notable mathematician and educator recognized for her work in the field of mathematics, particularly in algebraic topology and its applications. However, it's important to clarify that there may be limited publicly available information about her specific contributions.

Eduardo Torroja Caballe is a notable Spanish engineer and architect known primarily for his work in the field of structural engineering. He is recognized for his contributions to the design of innovative and aesthetically striking structures, particularly in the use of concrete and lightweight design principles. Torroja's legacy includes a number of significant projects, often praised for their engineering excellence and architectural beauty.

Hamnet Holditch is not a widely known term or concept. However, it might refer to Hamnet, the son of William Shakespeare and Anne Hathaway, who died at a young age. There is a novel titled "Hamnet" by Maggie O'Farrell that explores the family's dynamics and the impact of Hamnet's death on Shakespeare's work.

Karl Georg Christian von Staudt (1798–1867) was a German mathematician known for his contributions to projective geometry and for foundational work in the field of geometry as a whole. He is particularly noted for his work on the algebraic aspects of geometry and the development of what is now recognized as projective geometry. One of Staudt's significant contributions is his formulation of Staudt's theorem, which relates to the duality principle in projective geometry.

Rudolf Luneburg is likely a misspelling or confusion regarding "Rudolf Lünenburg" or "Lüneburg." Lüneburg is a town in Lower Saxony, Germany, known for its historical significance, medieval architecture, and salt production history.

As of my last knowledge update in October 2021, Samuel L. Greitzer does not appear to be a widely recognized public figure, historical personality, or notable individual. It is possible that he is a private individual or someone who has gained prominence after that date.

Ion Barbu (1895–1961) was a prominent Romanian poet, mathematician, and translator. He is known for his contributions to Romanian literature, particularly in the modernist movement. Barbu's poetry is characterized by its innovative use of language, complex imagery, and abstract themes, often exploring existential and philosophical questions. In addition to his literary work, Ion Barbu made significant contributions to mathematics, especially in the fields of geometry and topology.

István Fáry (1916–2001) was a Hungarian mathematician recognized for his significant contributions to topology and combinatorial geometry. He is particularly known for his work related to the Fáry graph and for Fáry's theorem, which states that every simple planar graph can be represented in the plane by straight-line segments without any crossings. Fáry's contributions extend to various mathematical fields, and he has published numerous papers throughout his career.

Jacques-François Le Poivre (also known as Jacques-François Le Poivre de Flesselles) was a French chemist and biologist known for his work in the field of natural history and botany during the 18th century. He is particularly noted for his studies related to the properties and uses of various plants, including spices. His contributions to the understanding of plant sciences were significant during this period, aligning with the broader scientific explorations of the Enlightenment.
