Vladana Likar-Smiljanić (Serbian Cyrillic: Владана Ликар-Смиљанић) (born July 18, 1943 in Belgrade, Yougoslavia) made a variety of contributions, most famously as an illustrator of children’s books but also in electrical engineering. Vladana’s versatility was foreseen in her childhood, as Leonardo da Vinci has fascinated her since then.Vladana is among the best-known illustrators in the former Yugoslavia, where she illustrated children’s books that were sold in hundreds thousands of copies. Exact numbers of sold copies are hard to know due to the unruly nature of the Balkans especially in uncertain political times. Vladana’s books were sold also in Spain, Italy, the United States, Germany, Soviet Union. Initially, she became well known for her page “Cica’s Corner” in a popular Yugoslav magazine for entertainment Politikin Zabavnik.Vladana’s first and most famous book is “The Treasury of Children’s Poems by Jova Jovanović Zmaj”. This book alone was sold in several hundreds thousands copies. After her successful debut, Vladana illustrated more than twenty books that were almost as popular as her first book.She was collecting counting songs for the hide and seek game of many nations, and illustrated those in one of her favorites “Counting Songs”. Vladana both wrote and illustrated her last book “Princess Milly” that was devoted to her younger daughter Milče. Milče was somewhat frightened little girl, and the stories of this book were weaved to encourage her to handle whatever situations she would encounter.Vladana’s “real” job was teaching and researching at University of Belgrade's School of Electrical Engineering. She was a popular teacher. For her research, she was examining the properties of various materials, in particular their complex permeability and permittivity at high frequencies. She published quite a few papers in the prestigious international journals. Vladana is a coauthor of two textbooks in the area of microwave communications.Vladana’s political work during Milošević governance in Serbia is another aspect of her contribution to the society. It was noted by Human Rights Watch, and Helsinki Committee for Human Rights. Finally, Vladana became a director of the computing center at the School of Electrical Engineering of Belgrade University in 2001, that was quite devastated at the time by the anti-university politics during the previous decade. Vladana helped the computing center reach the world standard.Modern times of narrow professional specializations did not influence Vladana, she is persistent following the Da Vinci polymathic way (art+engineering+politics).
