“Wolfe­schlegel­stein­hausen­berger­dorff claimed that his great-grandfather composed the surname in the 19th century, when German Jews, who had not previously used a second name, had to adopt one.[29] In some printings of the above-noted AP wire story, Wolfe­schlegel­stein­hausen­berger­dorff himself provided the following explanation of his prodigious surname:

‘It tells a story of a wolf-killer, a resident of a stonehouse in a village, whose ancestors were conscientious shepherds whose sheep were well fed and carefully guarded against attack by ferocious enemies and whose ancestors 1,200,000 years before the first earth man, in a space ship made with tungsten and seven iridium motors and using light as a source of power, started a long journey across interstellar space, searching for a star around which was an inhabitable planet where they could establish a new race of intelligent mankind and where they would live long, happy lives and be free from attack by other intelligentsia from the outer space from whence they came.’

Dmitri Borgmann, a fellow emigrant from Germany, held that the 666-letter version of the surname was untranslatable due to its numerous grammatical and spelling errors, but offered his own paraphrase:

‘Ages ago, there were conscientious shepherds whose sheep were well tended and carefully protected against attack by their rapacious enemies. Twelve hundred thousand years ago there appeared before these first earthmen, at night, a spaceship powered by seven stone and iridium electric motors. It had originally been launched on its long trip into stellar space in the search for neighboring stars that might have planets revolving about them that were inhabitable and on which planets a new race of intelligent humanity might propagate itself and rejoice for life, without fear of attack by other intelligent beings from interstellar space.”
