Who first proposed the kingdom Protista?

The German zoologist Ernst Haeckel (1834–1919) first proposed the kingdom Protista in 1866 for the newly discovered organisms that were neither plant nor animal. The term “protist” is derived from the Greek term protistos, meaning “the very first.” (For more about protists, see the chapter “Bacteria, Viruses, and Protists.”)
