Kenneth Craig Holland (? – ?) led the group developing components and contributed technically for many years.

Contributions include cam switches (originally allegedly the idea of Howard Vollum, but improved numerous times by Ken and group), high speed attenuators, Tek relays, and probes from early 1970s onward.

The probe for the 7A11 was designed by Ken Holland's group, with Ron Peltola serving as the engineer.
