**June 10:**

*Math News:* In 1854, Riemann defends his Habilitation to Gauss (on the foundations of Geometry), qualifying Riemann to supervise doctoral students. (See MathDL for details.)

*Deaths: *Andre Marie Ampere (1775-1836)

**June 12:**

*Birthdays: *Zygmunt Janiszewski (1888-1920)

**June 13:**

*Math News:* In 1676, Newton writes to Leibniz stating for the first time the binomial theorem for fractional and negative exponents. (See MathDL for details.)

*Birthdays: *James Maxwell (1831-1879), John Nash (1928-present), Willebrord Snell (1580-1626)

*Deaths: *Hermann Wiener (1857-1939)

**June 14:**

*Birthdays: *Charles Coulomb (1736-1806), Andrei Markov (1856-1922), Atle Selberg (1917-2077)

*Deaths: *Colin Maclaurin (1698-1746)

**June 15:**

*Math News:* In 1752, Benjamin Franklin conducts his kite experiment. (See MathDL for details.)

**June 16:**

*Math News: *In 1799, at the age of 22, Gauss receives his Ph.D. His dissertation includes the first correct proof of the Fundamental Theorem of Algebra. Because of its significance, the oral examination requirement is waived. (See MathDL for details.)

**June 17:**

*Birthdays:* M.C. Escher (1898-1972)

**June 18:**

*Math News:* In 1983, Sally Ride becomes the first American woman in space. (See MathDL for details.)

**June 19:**

*Birthdays: *Blaise Pascal (1623-1662)

**June 20:**

*Deaths:* Abraham Kastner (1719-1800)

**June 21:**

*Birthdays: *Simeon Poisson (1781-1840)

**June 22:**

*Math News:* In 1633, Galileo recants the Heliocentric Model of the Solar System. (See MathDL for details.)

*Birthdays:* Hermann Minkowski (1864-1909)

*Deaths:* Felix Klein (1849-1925)

**June 23:**

*Birthdays:* Alan Turing (1912-1954)

*Deaths:* Wilhelm Weber (1804-1891)

**June 24:**

*Birthdays:* Oswald Veblen (1880-1960)

**June 26:**

*Birthdays: *William Thomson – Lord Kelvin (1824-1907)

*Deaths:* David Rittenhouse (1732-1796)

**June 27:**

*Deaths:* Sophie Germain (1776-1831)

**June 28:**

*Math News:* In 1997, Andrew Wiles is awarded the Wolfskehl Prize for his proof of Fermat’s Last Theorem. (See MathDL for details.)

*Birthdays: *Henri Lebesgue (1875-1941)

**June 29:**

*Math News:* In 1877, Cantor writes to Dedekind stating that he has proven that there is a one to one correspondence between the points in a square and the points on a line segment. (See MathDL for details.)

**June 30:**

*Math News:* In 1742, Goldbach writes to Euler stating his now famous conjecture, “every even number greater than two is the sum of two primes.” The conjecture is now known as Goldbach’s Conjecture. (See MathDL for details.)
