An experimental <condensed matter physicist> who, with <Don Eigler>, demonstrated controlled positioning of individual <xenon> <chemical atoms> on a <nickel> surface in 1990. Their <scanning tunneling microscope> operated at 4 K: its tip became a tool for constructing arrangements one <chemical atom> at a time, extending the instrument's role beyond imaging. This established a practical route to studying deliberately assembled structures on surfaces.<Positioning single atoms with a scanning tunnelling microscope by Don Eigler and Erhard Schweizer>[Abstract: individual xenon atoms, single-crystal nickel, 4 K and atom-by-atom structures]{ref}
