I am not sure if I was the first, but I defined T-algebras for an
endofunctor T in my paper, Coequalizers and free triples. You can find it
at http://www.math.mcgill.ca/barr/papers/#1970s, it being my first 1970s
paper. As the name suggests, the category of T-algebras is often
tripleable.

Does anyone know who was the first author to speak about F-algebras
and/or F-coalgebras where F is a mere endofunctor? Lambek proved his
famous lemma without using any name for the objects. And Arbib and Manes
proved a number of properties but used the word "F-dynamics".
Thanks Jiri
