7 lives in this collection worked in projective geometry, from 290 to today. Each has a full course on their life and the mathematics and physics they made.
Often together with: astronomy, combinatorics. All fields
Alexandrian geometer whose Mathematical Collection preserved much of Greek geometry and contains the hexagon theorem, the cross-ratio lemma and the centroid rule for solids of revolution.
geometry, projective geometry, mechanics
Lyon engineer and architect whose 1639 Brouillon project on conics founded projective geometry and whose theorem on perspective triangles underlies the foundations of geometry.
projective geometry, perspective, architecture
Mathematician, physicist and writer who proved the hexagram theorem, built the Pascaline, established atmospheric pressure, co-founded probability theory with Fermat, and wrote the Provincial Letters and Pensées.
projective geometry, probability theory, combinatorics
Engineer officer who founded modern projective geometry with his 1822 Traité and made work the central concept of the mechanics of machines.
projective geometry, applied mechanics, hydraulic engineering
Leipzig astronomer and geometer who introduced barycentric and homogeneous coordinates, the Möbius function and Möbius transformations, and described the one-sided Möbius band.
projective geometry, astronomy, topology
French geometer and historian who systematised projective geometry around the cross-ratio, proved the screw theorem for rigid motions, founded enumerative geometry with the number 3264, and was the victim of the Vrain-Lucas forgeries.
projective geometry, enumerative geometry, kinematics
Self-taught Swiss geometer who became the leading synthetic geometer of the nineteenth century, known for the projective generation of conics, symmetrization, Steiner chains and Steiner systems.
