Dear Eno and the entire Cornelisen family, I am so sorry that Erika left us too soon. She was such a fighter, a beautiful wife and an amazing mother. We are all going to miss her but she left a wonderful legacy of love and support for science. May her soul rest in peace.

I was so sorry to see the notice of Erika's passing in the Herald. Erika was one of the most delightful young people I ever had the pleasure of knowing. Her spirit, her character, her talent, they all combined to make her an extraordinary human being at a young age. I'll always remember her telling me about her family summer home in Pentwater, which we enjoyed renting several times when our sons were young.
