The third of four siblings, Fouad al-Mohandes was born to a father who was a linguist, a professor at Dar al-Ollum, (the Arabic College) and a member of the Arabic Academy. As a child, al-Mohandes was mostly influenced by his father, from whom he inherited his wit and humour.

Al-Mohandas studied at the Faculty of Commerce, Cairo University, where he joined the drama group. His life was turned upside down, however, after he watched the great Naguib al-Rihani performing on stage. Later, he became one of his followers.

In 1953, after al-Rihani's death, the program "An Hour for your Heart" was launched grouping many of Egypt's comedic actors of the time, including al-Mohandes. Having lived close to the Zul-Foqqars, the two brothers Mahmud and Ezz, they signed him up for several supporting roles in movies they directed including the "Neighbour's Daughter", "The Good Land" and "The River of Love", among others .

In the early 1960s, the Egyptian television began its broadcast. It was then that he became famous in his role in the program "Behind the Curtains" opposite actress Sanaa Gamil. Al-Mohandas later joined television theatres. His major breakthrough was when he took the lead role in a new version of al-Rihani's play al-secretair al-fanni (The Technical Secretary) starring another entrant to the world of entertainment and show business Showikar Toub Saqqal, who later became his wife.

In all his plays and movies, al-Mohandes' motto was "Entertainment for the Sake of Entertainment". His version of "My Fair Lady" earned him a great deal of acclaim.

In the 1950s, as the nation faced numerous economic and political challenges, private sector theatres were interested only in providing entertainment to the public. This is where al-Mohandas mostly excelled.

Al-Mohandas died in 2006 at the age of 82.
