Mehmet Nadir

He was born in Sakız island (modern Chios in Greece) then a part of the Ottoman Empire, to a poor family.

But when Sultan Abdülhamit II arrested 350 Young Turk adherents on the charge of planning a coup in 1896, Mehmet Nadir was forced to resign.

After working in a public school in Istanbul in 1903, he was appointed to Aleppo (now in Syria) as the director of education.

After he convinced Young Turks of his innocence, he was appointed mathematics professor in the newly established Girls' University in Istanbul.

In 1919 soon after the World War I, he began serving in the Darülfünun (present day, Istanbul University) as a müderris (professor) of mathematics in the newly established branch of Number theory.

[4] He actively participated in a group of mathematicians of a French mathematics periodical named I’Intermediaire des Mathematiciens.
