Brian Henderson Professor Emiritus, Strathcyde University Home address: 5 Raynhams High Street Saffron Waldon Essex CB10 1AT Brian Henderson graduated with B Sc (1958) and Ph D (1962) at Birmingham University, England. Researches into the spectroscopic properties of point defects and paramagnetic ions in insulating materials led to appointments at AERE Harwell, as Reader in Physics at Keele University, Professor of Natural Philosophy at Trinity College, Dublin and Professor of Photonics at the University of Strathclyde in Glasgow. He has more than 200 publications including books, critical reviews and refereed journal articles. He retired in 1997. George F. Imbusch Professor Emiritus National University of Ireland, Galway University Road Galway Ireland Frank Imbusch obtained the BSc (1956) and MSc (1958) degrees at University College, Galway, after which he carried out graduate research for his Ph D (1964) at Stanford University with the Nobel Laureate Art Schawlow. His researches on high resolution optical spectroscopy of transition and rare earth metal ions in solid state hosts continued at the Bell Laboratories before his return to Galway as lecturer in Physics in 1967. He was promoted there to Professor of Experimental Physics in 1976 and retired from the Department of Physics in 2000. He is at present Academic Research Officer at the Royal Irish Academy.
An excellent introduction to the theoretical and experimental aspects of solid-state spectroscopy. --David R. Foster, American Scientist This book has been carefully and clearly written and is attractively produced...an excellent introduction to the subject. --William Hayes, Journal of Modern Optics A worthy general account. --Peter Day, The Times
