KittyCatS History: Who discovered what & when?

[Deer Thistle]

Hi everyone! I noticed that the Prismatic eye has been pulled over the past few days but can anyone offer concrete information about its discovery? It'd be so appreciated, I noticed the KittyCats Addicts group didn't provide any notice on its initial discovery too which leaves me even more in the dark. Thank you to everyone who has been so helpful in piecing together this chart thus far!
