Asteroid 564 Dudu was discovered on May 9th, 1905 by Paul Götz at Heidelberg, a hotbed of minor planet detecting at the time. It is in the main belt, and measures about 49 to 50 km across.
The name Dudu comes from that of a fictional cat in Also Sprach Zarathustra by Friedrich Nietzsche, a work in which humans are seen as being at a halfway stage between apes and super- or over-humans. Nietzsche obviously never watched Britain’s Got Talent.
Also today we have asteroid 565 Marbachia, discovered by Max Wolf, himself a veritable übermensch among asteroid hunters. Marbachia (named after Marbach, Germany) was also discovered at Heidelberg, possibly on the same telescope as Dudu.
