Did you know that John Kellogg, the inventor of your morning cereals, enjoyed loading up yoghurt into people's rectums at 14 liters per minute?

"Kellogg ordered his patients to produce 4 or more bowel movements a day, just like the healthy apes he had once observed while on a safari in Africa. The son of a broom manufacturer, Kellogg was obsessed with bodily cleanliness, both external and internal."

"Kellogg dedicated the last 30 years of his life to promoting eugenics. He co-founded the Race Betterment Foundation,[7] co-organized several National Conferences on Race Betterment and attempted to create a 'eugenics registry'. Alongside discouraging 'racial mixing', Kellogg was in favor of sterilizing 'mentally defective persons', promoting a eugenics agenda while working on the Michigan Board of Health[8] and helping to enact authorization to sterilize those deemed 'mentally defective' into state laws during his tenure.[9][10]"
The whole family was quite weird.

"Only the members of the Contact Commission witnessed the activities of the "sleeping subject", and only they knew his identity.[10] The individual is claimed to have been kept anonymous in order to prevent undesirable future veneration or reverence for him.[26] Martin Gardner states that an explanation concerning the origin of the book more plausible than celestial beings is that the Contact Commission, particularly William Sadler, was responsible. Gardner's conclusion is that a man named Wilfred Kellogg was the sleeping subject and authored the work from his subconscious mind, with William Sadler subsequently editing and authoring parts.[27] Brad Gooch believes Sadler wrote the book, possibly with help from others on the Contact Commission.[28] A statistical analysis, using the Mosteller and Wallace methods of stylometry, indicates at least nine authors were involved in the Urantia documents. Comparing Sadler's The Mind at Mischief to the Urantia documents does not indicate authorship or extensive editing of the latter by Sadler, without ruling out the possibility Sadler made limited edits or contributions.[29]"

This one seemed the most normal. However, even though (above) "Wilfred" was considered the "sleeping subject" channeling heavenly hosts, I believe either it was this guy (misnamed or purposefully misidentified) or another Kellogg which was kept from the spotlight for risk of tarnishing the family legacy.
