Dragutin Bišćan (*  Friday 24.08.1923  -  † Tuesday 14.12.2004)

Croatian chess composer

Drago composed direct mates, helpmates and selfmates problems. Let's just quote this homage by Nikola Predrag [broken link] just after his death:

"For the achievements in pedagogy, journalism and chess composition he was highly awarded. He earned the title of national chess problem master in 1971. More than 500 of his compositions were published, one fourth of them awarded, in various domestic and international magazines. Croatian problemists have lost a deserving colleague and above all a good friend. The inspiring memory of Drago Biscan, his animating temper and unique art, remains vivid."
