C. L. Lehmus
Daniel Christian Ludolph Lehmus (July 3, 1780 in Soest – January 18, 1863 in Berlin) was a German mathematician, who today is best remembered for the Steiner–Lehmus theorem, that was named after him.
Lehmus was the grandson of the German poet Johann Adam Lehmus (1707-1788) and the Berlin-based physician Emilie Lehmus (1841-1932) was his grandniece.
His father Christian Balthasar Lehmus was a science teacher and director of a gymnasium in Soest, as such he took it upon himself to school his son.
From 1799 to 1802 Lehmus studied at universities of Erlangen and Jena.
In 1803 he went to Berlin, where he was giving private lectures in mathematics and pursued further studies at the university, which awarded him a PhD in 1811.
From December 18, 1813 to Easter 1815 Lehmus was employed as a lecturer (Privatdozent) by the university, but in 1814 he became a teacher for math and science at the "Hauptbergwerks-Eleven-Institut" (mining school) in Berlin as well.
In 1826 he also assumed a teaching position at the " Königlichen Artillerie- und Ingenieurschule" (military engineering school) and was granted the title of a professor at that school in 1827.
In 1836 he was awarded the Order of the Red Eagle (4th class).
In addition to his two teaching positions Lehmus was giving lectures at the university until 1837 as well.
Lehmus wrote a number of math and science textbooks, best known was probably his "Lehrbuch der Geometrie", which saw several editions.
He published articles in various math journals, in particular he was a regular contributor to Crelle's Journal and provided an article for its very first edition in 1826.
He published an elegant trigonometric solution of Malfatti's problem in the French math journal "Nouvelles Annales de Mathématiques", but due to a copy error the author's name was given as "Lechmütz".
In 1840 Lehmus wrote a letter to the French mathematician C. Sturm asking him for an elementary geometric proof of the theorem that is now named after him.
Sturm passed the problem on to other mathematicians and Jakob Steiner was one of the first who provided a proof.
In 1850 Lehmus came up with a different proof on his own.
The theorem itself proved to be a rather popular topic in elementary geometry being a subject of somewhat regular publications for over 160 years.

R. A. McConnell
Robert A. McConnell( 1914—2006) was an American physicist and parapsychologist.
McConnell was born in Pennsylvania in 1914, and studied at Carnegie Institute of Technology obtaining a B.S. in physics in 1935 and a Ph.D. from the University of Pittsburgh in 1947.
He worked as a physicist at a U.S. Naval aircraft factory and at the Massachusetts Institute of Technology Radiation Laboratory.
He also worked in radar moving target indication, iconoscope, and ultrasonic microwaves.
He earned a Doctor of Philosophy degree in engineering physics.
McConnell was the first president of the Parapsychological Association and a Fellow of the American Psychological Society.
He was Research Professor Emeritus of Biological Sciences at the University of Pittsburgh.
David Ji
David Longfen Ji is an American businessman who co-founded Apex Digital, an electronics manufacturer.
In 2004, he was arrested in China following a dispute with Sichuan Changhong Electric, a supplier owned by the city of Mianyang and the province of Sichuan.
Changhong accused him of defrauding them through bad checks.
Ji was taken, according to an account by his lawyer, to the senior management and told, "I decide whether you live or die."
He has been held in China without charges.
Ji's case highlighted an "implicit racism" in dealings with American businessmen.
As a U.S. citizen he was not granted the same treatment by authorities as non-ethnically Chinese businessmen sharing the same nationality.
