Builders Instead of Consumers: Training Astronomers in Instrumentation & Observation

The astronomy community has made clear our shared scientific vision in the Astro2010 decadal survey. Who will build this future? The cost and scarcity of telescope resources makes vital learning through doing extremely difficult for students and early career researchers. What is needed now and in the future to provide a depth of knowledge, creativity, and experience in our field? At McDonald Observatory we have a clear model in answer to that question, and a long history of successfully training the next generation of instrument builders and observers. We must support and sustain small to medium range local resources such as McDonald to foster the successful growth of our field.
