Yes, Mr Wolfe+585 is 'senior', he gave the exact same name to his son, Hubert Blaine Wolfeschlegelsteinhausenbergerdorff, Jr., who learnt to pronounce his full name by the age of 3.
Wolfeschlegelsteinhausenbergerdorff was born in Bergedorf, Germany (a part of today's Hamburg), and later emigrated to the United States, settling in Philadelphia. His birthdate has been given as February 29, 1904, but he was also reported to be age 47 in a mid-1964 wire story. He became a typesetter, "logically enough", according to Bennett Cerf. He was a member of the American Name Society for a while.
He appeared in all editions of the Guinness Book of World Records from roughly 1975 to 1985 as having the longest personal name, and was photographed for the book in front of a New York City marquee displaying his name, once again misspelled. By 1983, only the 35-letter form of the name appeared in the Guinness Book; in the late 1980s, the category disappeared.
