The first time I met Karl 

 

Contribution by Lois Weyer

 

The first time I met Karl was when he and I were standing in line to register at a hotel, probably in Chambersburg on a weekend before one of the early symposia. I was awe-struck at meeting the person who started the whole field of modern NIR and he was very kind and friendly. He continued to be helpful and welcoming to me, as a newcomer. And, we proceeded to see derivatives in the same way throughout the following years.
