Thomas Harriot (1560-1621)

  • Born in England.
  • He was instrumental in extending and codifying the theory of equations.
  • He was the first to use > and to indicate greater than and less than.
Felix Hausdorff (1862-1942)

  • Born in Germany.
  • He developed the branch of mathematics known as topology.
  • He formaulated a maximal principle in general set theory.
Jacques Herbrand (1908-1931)

  • Born in France.
  • He formaulated a theory which established a link between quantification theory and sentential logic.
Charles Hermite (1822-1901)

  • Born in France.
  • He applied elliptic functions to find solutions of the quintic equation and of Lamé’s differential equation..
  • He discussed the theory of associated covariants in binary quantics and the theory of ternary quantics
Heron (Hero of Alexandria) (fl. 62 CE)

  • Born in Egypt.
  • His formula provides the area of a triangle when the lengths of the three sides are known, but the height is not known.





David Hilbert (1862-1943)

  • Born in Prussia.
  • He solved all the known problems of algebraic invariants.
  • He introduced sweepng developments and new areas for research in algebraic topography.
Hipparchus of Rhodes ca. 180 – ca. 125 BCE)

  • Born in Greece.
  • His mathematical computations to chart the sun, moon, and stars led to his being named the founder of trigonometry.
  • He is also considered the founder of Greek astronomy.
Hippias (fl. ca.420 BCE)

  • Born in Greece.
  • He invented a curve called the quadratrix, by the means of which an angle can be divided into any given ratio.
Hippocrates of Chios (fl. 2nd half of 5th century BCE)

  • Born in Greece.
  • He is credited with the first exposition which developed the theorems of geometry and logically from a few given axioms or postulates, in Elements.
  • He formulated the quadrature of the lune, that is, the construction of a square having area equal to that of the original plane figure, using only a compass and a straightedge.
John de Holywood (Sacrobosco) (ca.1200 – ca.1256)

  • Born in England.
  • His work on arithmetic was a standard authority for many years
Hypathia (370-414 CE)

  • Born in Egypt.
  • Very little is known of her work, although it is believed that she was an algebraist.
  • She seemed to have had an interest in conic sections.
