Harlyn Halvorson and Holger Jannasch were both interested in the origin of life and evolution. Thus, their interests also melded with Esther's interest in life and biochemistry both on the earth and outside the earth, as studied by such people as Aleksandr I. Oparin. This interest was expressed well before the term "exobiology" was coined.1,2
