		| Abstract: | 
		The decade 1993-2003 was a particularly exciting time to be at Cerro Tololo 
 - for most staff members.  Tough times at the beginning involved significant 
 staff reductions - the worst moment of my professional career. In return, the 
 observatory was granted a period of stability in which it was possible to 
 rebuild morale, which in turn helped the research climate to recover rapidly.  
 Emphasis was given to improving the image quality at the Blanco 4m (led by 
 Jack Baldwin), while quietly supporting efficient operation of the smaller 
 telescopes (led locally by Alistair Walker) via the development of the SMARTs 
 consortium.  In 1998 came the high point - the announcement of the discovery 
 of Dark Energy that showed us all how much we still have to learn about the 
 universe; this work depended crucially on the work of staff members at CTIO 
 and staff and students from Chilean and Argentinian universities (as described 
 elsewhere at this conference).  The Inter-American nature of CTIO also laid 
 the crucial groundwork (in which Joao Steiner was a key player) for Brazil's 
 involvement in SOAR and Gemini.  Work during the period to minimize the 
 advance of light pollution over Cerro Tololo (and the rest of northern Chile) 
 helped create a credible case for siting the LSST on Cerro Pachón. |
