Roknuzzaman Khan (born: 9 April, 1925 - died: 3 December, 1999) was an established writer and organizer of Bangladesh. He was widely known as Dadabhai. Dadabhai Roknuzzaman Khan, beloved by young and old alike, was born on 9 April 1925 in Pangsha upazila of Rajbari district into a family rich in literature and culture, and his life passed in a similar environment. Dadabhai's ancestral home is in Bhabanipur village of Bheramara thana in Kushtia.
He was born in the home of the famed literary figures and editors of that era, Rowshan Ali Chowdhury and Eyakub Ali Chowdhury. They were Dadabhai's nanas (maternal grandfather and granduncle). His father's name was Moulvi Mokhair Uddin Khan. Losing his mother in childhood, he grew up at his maternal grandfather's home and studied at Pangsha George School. He then moved to Calcutta.
Roknuzzaman Khan Dadabhai began his career in 1947 through the daily Itehad of Calcutta. In 1948 he began his working life by taking charge of the children's section of the Itehad paper named 'Mitali Majlish', edited by Abul Mansur Ahmad. He then served as acting editor of the children's magazine Shishu Saogat. In 1952 he was director of the children's section 'Kishor Duniya' of the daily Millat. In 1955 he joined the Daily Ittefaq and began working as a young journalist, and he worked for this paper until the very moments before his death. On 2 April he was appointed director of the Daily Ittefaq's section for children and adolescents, Kochi-Kachar Ashor, and the director of the Ashor was named Dadabhai. From then on he gained a new identity as Dadabhai. Through his connections, many renowned writers wrote for this paper tailored to the young, including Sufia Kamal, Abdullah Al Muti Sharfuddin, Shawkat Osman, Ahsan Habib, Faiz Ahmed, Hosne Ara, Nasir Ali and Habibur Rahman. He worked tirelessly as director of the Daily Ittefaq's Kochi-Kachar Ashor section until his death.
He also edited for a long time a monthly magazine named 'Kochi Kancha'. The Kochi-Kachar Mela, founded by his hands in 1965, is today Bangladesh's largest children's and adolescent organization. Until his death he held the organization close to his heart like his own child. Children are the finest human resource; children are the angels of heaven. This Dadabhai is the craftsman who molds them into human beings. From childhood his dream was to create a paradise-garden for children. At this stage of life, that dream must be called fulfilled. Accomplishing that silver dream amid thousands of limitations and adverse circumstances is a difficult matter. Dadabhai made tireless sacrifices to achieve this goal and illuminated hundreds of thousands of children and adolescents with the light of heaven.
Few people as capable and devoted to children as he was have been born in this land. He spent his entire life thinking about children. The children shaped by his hands are today well established in national life. Until his death he thought about the children of tomorrow. Today's Bangladesh Shishu Academy was founded at his proposal. Besides the Kochi-Kachar Mela, Dadabhai served various organizations. Among these, the Shishu Kalyan Trust, Bulbul Lalitakala Academy, National Anti-Tuberculosis Association, Shishu Academy and Shishu Kalyan Parishad deserve special mention.
Roknuzzaman himself wrote many poems and rhymes, and corrected and edited children's writings for publication in newspapers. He made tireless efforts to unfold children's minds and develop their talents.
"Coo, coo, my little doves, tyres spinning overhead
Will the bride adorn herself tomorrow, will she ride the golden palanquin"
It has long been regarded as his outstanding children's rhyme. Hattimatim Tim, Khokon Khokon Dak Pari, Ajab Holeo Gujab Noy and others are his notable books. Jhikimiki, edited by him, is an important children's anthology. Through these works he tried to awaken moral wisdom, patriotism and virtues of character in the tender minds of children. He also edited books such as Amar Prothom Lekha, Barsik Kochi O Kancha and Chhotoder Abritti.
In family life, Dadabhai was the father of two daughters. His wife was Noorjahan Begum, editor of 'Begum', Bangladesh's greatest woman personality, who is well known to everyone in the country. His father-in-law Mohammad Nasiruddin, editor of Saogat, was a renowned figure.
In recognition of his creative and organizational work, Roknuzzaman Khan was honored with the Bangla Academy Award (1968), Shishu Academy Award (1994), Ekushey Padak (1998), the Jasimuddin Gold Medal, and the Paul Harris Fellowship honor of Rotary International and the Rotary Foundation Trustees. For his outstanding contribution to children's organizations, Roknuzzaman Khan was posthumously awarded the Independence Day Award in 2000.
Roknuzzaman Khan Dadabhai, beloved of the young, left everyone on 3 December 1999 for that unknown country from which no one ever returns. But though he is gone, everyone will remember his contributions.
