Gottlob Frege was a renowned German mathematician, logician, and philosopher of the 19th century. Many people considered him the greatest logician after Aristotle. He had done great work in the fields of maths, philosophy, and logic.
But he was ignored during his lifespan. He gained popularity after death by the efforts of Peano, Russell, and Ludwig. He contributed significantly to the logic branch of maths.
Time and place of birth
He was born on 8 November 1848. In Wismar, Grand Duchy of Mecklenburg-Schwerin, Germany.
He was born in the family of a teacher. Yes, his father was the headmaster and co-founder of a girl’s high school. Frege’s father’s name was Karl Alexander Frege and her mother was Augusta Wilhelmine Sophie Frege who took charge of that school after her husband’s death. This is the reason why he pursued a career in teaching and became a maths teacher later in his life.
In 1869 Frege became a graduate at the age of 21. In 1887 Frege married Margaret Katherine Sofia Anna Liseberg. Before his marriage, Frege became a private teacher of maths at Jena in 1874.
Frege died on 26 july 1925, in bad kleinen, mecklenburg-schwerin, germany.

Contribution in Mathematics
Frege’s early focus was geometry which later turned towards logic. Frege worked on logic which is different from Aristotle’s. Because he wanted to prove that mathematics grew out of logic. That’s why his logic is called mathematical logic. But previously logic was not connected to maths.
