**Work :**

★ Ada Lovelace's teacher introduced her to Charles Babbage(father of the computer) in 1833, their friendship grew strong with time. Later she became interested in his work **" Difference Engine".**

★ Charles Babbage delivered a lecture on his invention **"Analytical Engine" at 'University of Turin' in the year 1840.** A Luigi Menabrea, an Italian writer, wrote his above lecture in French, which was printed two years later in **'Bibliotheque universelle de Genève'**

★ Ada Lovelace translated his lecture to English as requested by Charles Whetstone. In the year 1842-43, Lovelace added points of her own analysis to the above-transcribed paper. The points she added are as follow:

a) She claimed Babbage's " Analytical Engine" is more advanced than other calculating machines, and it can perform a plethora of operations other than numerical calculations.

b) She wrote an algorithm to calculate **Bernoulli's number for** Babbage's "Analytical Engine ". It is Known to be the **world's first ever algorithm in computer programming. **

c) She also wrote about the drawbacks of "Analytical Engine", now considered the** predecessor of debugging.**

★ Apart from being a mathematician, she was also interested in **Phrenology (study of measurement of bumps on the human skull) and animal magnetism.**

★ She reviewed a research paper written by Baron Karl Von Reichenbach on "Animal Magnetism " in 1844, but it never got published.

★ She designed a model that could decode the neurological process involved in evolution of feelings using mathematics. She called it **"Calculus of the nervous system "** but unfortunately, it was not successful.

**Achievements:**

She is the first person to write the first algorithm program for Charles Babbage's Analytical Engine to calculate Bernoulli's number. Every** year, the second Tuesday of October, is celebrated as Ada lovelace day in her honor. It is an international celebration of women’s achievements in the Science, Technology, Engineering, and math(STEM) field.**

**Death of Ada Lovelace :**

Ada Lovelace died at a very young age of **37 on November 27, 1852,** due to uterine cancer. As per her request she was laid to rest next to her father's grave in Nottingham's 'Church of St Mary Magdalene '.

**Summary**

Ada Lovelace being brought up in a very strict and religious environment never let her dreams to fade. She wrote the world's first algorithm to calculate "Bernoulli's number" and had a very good work relationship with many famous scientists and mathematicians. Ada also reviewed many of their journal papers and works. She is an inspiration for women in STEM. Ada lovelace day is celebrated as a recognition of her achievements.
