Some names I'd add:
Cecilia Colledge-it was she that changed ladies skating from the choppy, bent knee, tippy toeing that Sonja Henie did to something that a Janet Lynn fan would recognize, including balletic spirals, lovely spread eagles, and footgrabbing spins:
When they make a rule about you, and when they completely eliminate a jump (the toe walley) from scoring because of you, you've changed skating. Elaine Zayak made multiple triple jumps in an LP required for the ladies.
In dance, really, the modern style goes back to Pakhamova & Gorshkov, Olympic gold medallists in 1976. They added the Drama to ice dance and created the Russian style, which has been a dominant force in ice dance ever since. A shoutout for the creation of 4 of the compulsory dances goes to the English couple of Wilkie and Wallis, who invented the Quickstep CD, the Foxtrot CD, the Argentine tango CD, & the paso doble CD, .
