Leonhard Euler, a Swiss mathematician, physicist, and engineer, is widely considered the greatest mathematician of the 18th century. Euler made significant contributions in a diverse range of fields including calculus, number theory, graph theory, geometry, and mechanics.

According to the Stanford Encyclopedia of Philosophy, Euler was “the preeminent mathematician of the eighteenth century and one of the greatest of all time.” He made groundbreaking discoveries in calculus and number theory, including the Euler-Mascheroni constant, Euler’s formula, and the Euler product formula. Euler is also credited with introducing modern mathematical notation.

A quote from mathematician Carl Friedrich Gauss praises Euler’s impact on the field: “Euler was the master of us all.”

Here are some other interesting facts about Euler:

- Euler was born in Basel, Switzerland in 1707 and began studying mathematics at age 13.
- He published over 800 works in his lifetime, including influential books like “Institutiones calculi differentialis” and “Introduction to the Analysis of the Infinite.”
- Euler suffered from vision problems throughout his life, eventually becoming blind in one eye.
- Despite losing his eyesight, Euler continued to work with the help of his sons and collaborators. He famously described mathematics as “a blind alley” since it was possible to do so much without actually seeing the mathematical objects.
- Euler was a prolific letter writer, corresponding with hundreds of colleagues and friends throughout his lifetime. His correspondence has been preserved and provides valuable insights into his life and work.

Here is a table summarizing some of Euler’s major contributions to mathematics:

Field | Contribution |
---|---|

Calculus | Euler’s formula, Euler’s method, Euler’s equations |

Number theory | Euler-Mascheroni constant, Euler’s totient function, Euler’s theorem |

Graph theory | Euler’s polyhedral formula, Eulerian paths and circuits |

Geometry | Euler line, Euler angles, Euler’s disk |

Mechanics | Euler’s equations of motion, Euler’s buckling formula |

Leonhard Euler (1707-1783) was arguably the greatest mathematician of the eighteenth century (His closest competitor for that title is Lagrange) and one of the most prolific of all time; his publication list of 886 papers and books may be exceeded only by Paul Erdös. Euler’s complete works fill about 90 volumes.
