To my dearest wife Marianne Faircloth Johnson and our remarkable son Rutherford Barry Johnson for their gentle encouragement and support.
In memory of my parents, J. Ralph and Sara F. Johnson,
for their enduring tolerance of my often trying inquisitiveness.
And
In memory of Rudolf Kingslake (1903–2003),
who taught me to appreciate the beauty in well-designed lenses.
