He moved to the northwest of the country to pursue further education and graduated from Mogadishu University, producing his first work when he was 18 years old.
Yamyam was recognized as an influential Somali poet and playwright whose creative output did not wane after the state's collapse and subsequent civil war, which continued for a decade and a half.
He lived in Mogadishu and continued to write poems and articles for Somali websites and newsletters on the misfortunes that befell Somalia, which was one of Africa's strongest countries during the post-colonial era.
Yamyam, like most other gifted entertainers, used his poetic talents to highlight the misfortunes that befell his fellow Somalis as a result of the civil war and the ensuing chaos.
Although Yamyam was a patriot, he often reflected European colonial past wrongdoings from 1884 Africa divisions to the 1894 "Tripartite Accord" from Britain, Italy and Ethiopia.
His poetry reflected radicalism and dislike for the misuse of power and misappropriation of public funds of the toppled regime in Somalia in the 1970s and 1980s.
He was one of the main entertainers at the 2007 annual Somali Community gathering honoring youngsters who achieve great academic success.
Unlike most Somali poets, Yamyam penned down all his literary work starting from early on before he won the first academically conducted poetry competition held in Hargaisa.
Many people believe Yamyam was a long ago deceased poet at the time of Hooyaaleey style Somali poetry during the mid eighteenth century at time of Raage Ugaas and others because of in-depth content which he is unique for in his field as a great poet coupled with the academic work which he penned down, for example, his first play co-authoring with Ahmed Farah Ali 'Idaja', using the newly created Somali orthography.
Yamyam grew up in Hargaisa, but he remained in Mogadishu for much of his working life, including a decade and a half, a period when the Somali civil war years were at a climax.
When it came to showing his patriotism, Yamyam gave hours of poetry entertainment and a dose of reality for the year-long Arta Somali Peace Conference.
Abdulkadir Hersi Siyad, better known by his nickname Yamyam, died in a car accident in Columbus, Ohio, United States, aged 60.
