Biography Of Euclid


Euclid (325 BC – 265 BC), a Greek Mathematician, is considered to be the “Father of Geometry”. His book ‘Elements,’ a mathematics textbook he wrote, remained an influential text until the 19th century and is still one of the most popular books in the world. It is a classic in the sciences, particularly mathematics. According to Michael H. Hast, Euclid is the 14th most influential person in history.

Euclid was born around the 4th century BC in Alexandria and was active during the reigns of Ptolemy I (332-383 BC). His name Euclid means “respected, glorious”. He is also known as Euclid from Alexandria.

The details of Euclid’s childhood are not available. The main biographical information, such as his birth date and age, was not published until many centuries later. Proclus c. 450 AD. Proclus wrote about Euclid.

“Euclid was not much older than Plato’s pupils. He put together the “Elements”, placing in order many of Eudoxus’s theories, perfecting many of Theaetetus’s, and also making irrefutable demonstrations of things that had only been loosely proven by his predecessors. This man lived during the age of the first Ptolemy. Archimedes who closely followed the first Ptolemy mentions Euclid. They also say that Ptolemy once questioned him about a shorter way to study geometry than using the Elements. He replied that there wasn’t a royal road to geometry.

It is possible that Euclid collaborated with mathematics experts in Alexandria, and received some assistance in his mathematical work. While some historians believe that Euclid’s works may have been the work of multiple authors, most agree that Euclid was the primary author.

Euclid would probably be studied at Plato’s Academy, in Athens. Much of his first knowledge would have come through this Plato perspective. Eudoxus would have taught Euclid a lot of geometry.

Another historian, Pappus, writes about Euclid in 320 AD. He states that Euclid was a good character and that Euclid was:

“..most fair and well-disposed towards all who were capable in any measure of advance mathematics, careful not to take offense and even though a precise scholar, not boasting himself.”

While little is known about Euclid’s private life, his major book the Elements’ which was originally written in ancient Greek became a standard text of important mathematical teachings. It is divided into thirteen books.

Books 1 to 6 deal with plane geometry.
Books 7 to 9 deal with number theory
Book eight is about the geometrical progression
Ten deals with irrational numbering
Books 11-13 deal with three-dimensional geometry.
Euclid’s genius was to combine the many mathematical ideas that were in circulation into one coherent, logical format.


The most important aspects of Euclid are:

His prime number of work
Euclid’s Lemma – This states that prime numbers must be able to divide the product of at least one number.
The fundamental theorem of arithmetic or the unique-prime-factorization theorem. Euclid’s Lemma states that any integer greater than 1 is either a prime itself or the product of prime numbers and that there is a definite order of primes.
“If two numbers are multiplied by one another, they make some number. Any prime number measures the product. It will also measure one of the original numbers.”

The Euclidean algorithm is an efficient way to compute the greatest common divide (GCD), of two numbers. It’s the largest number that divides both without leaving a remainder.
Geometry. Euclid described a system for geometry that dealt with shape, relative positions, and the properties of space. Euclid was the one who arranged geometry in axiomatic forms or logically derived theories. His work is known for Euclidean geometry.
Sometimes it is said that the Elements may be the most widely translated, published, and studied book in the West.

Some believe that The Elements by Euclid is the second most widely published, translated, and studied book after the Bible.

Euclid was not only an expert on the Elements but also studied other branches of mathematics.

Optics Euclid analyzed the apparent size and distance between the eye and an object. Proposition 45 stipulated that objects of equal sizes should be compared to one another at a point.

Phaenomena– A work on Spherical Geometry – Spherical geometry is used to observe objects in space and create measurements.

Divisibility of Figures– Divide figures into more parts.

Data– Examining the information given from geometrical problems.
