John Ellicott is the 56-year-old[1] reclusive[2] father of Hannelore Ellicott-Chatham and a wealthy retiree whose most recent hobby was textiles.[3]

According to Hannelore, he spends most of his time on his own space station, where Hannelore grew up.

Like his daughter, he appears to have mental health problems.[4]

The longest arc mentioning him prior to The Birthday Party story arc[5] was the one in which he built a "robot boyfriend" for Hannelore.[4]

Doctor Ellicott was notable for several major technological advances (according to Strip 1902):

  • Developed the first "true" AI (the foundation of his fortune)[6]
  • Developed the quasiperpetual myomer
  • Pioneered sustainable AI-controlled orbital habitats
  • Designed microsatellites that keep the Earth's albedo stable
  • Invented the Robot Hamster
  • Created swarms of cancer-fighting nano-machines[7]

He has designed at least one robot prosthesis.[8] He also developed a paranormal containment field in 1984.[9]

Dr. Ellicott made his first actual appearance in the strip looking for his MP3 Player after Marten, Hannelore and Marigold met him.[10]

Hannelore's dad is only referred to as "Doc" in one strip, when Lt. Potter was talking to Space Station about his actions in her first appearance in the strip.[11]
