She gave me ahuge leap of faith when she sent me ofi to Fermilab the flrst time, and I don’t think I everthanked her for that. She then supported me during my graduate years in any imaginableway while allowing me the greatest possible freedom in choosing my research according to mypersonal interests. Those interests of mine led to 18 months worth of projects concerning thedevelopment of software for the ATLAS experiment, and I enjoyed tremendously to work withDr. Gun˜ ter Duckeck and Alexander Brandt during that time. I am thankful to Dr.
