The observation of the production of antihydrogen atoms \overlineH 0\equiv\barpe+, the simplest atomic bound state of antimatter, is presented. A method has been used by the PS210 collaboration at LEAR which assumes that the production of \overlineH0 is predominantly mediated by the e+e--pair creation via the two-photon mechanism in the antiproton--nucleus interaction. Neutral \overlineH0 atoms are...
