Osama's father started his professional life in the 1930s in relative poverty,working as a porter in Jeddah, Saudi Arabia. During his time as a young laborer, Mohammed impressed the royal family with his work on their palaces, which he built at a much lower cost than any of his competitors could, and with a much greater attention to detail. By the 1960s, he had managed to land several large government contracts to build extensions on the Mecca, Medina and Al-Aqsa mosques. He became a highly influential figure in Jeddah; when the city fell on hard financial times, Mohammed used his wealth to pay all civil servants' wages for the entire kingdom for a six-month period. As a result, Mohammed bin Laden became well respected in his community.
