Genealogy
We are interested in genealogy since we are both of Dutch ancestry. Our grandparents or great-grandparents came to the United States from the Netherlands in the mid 1850's. We now have our ancestry in both families back from 6 to 12 generations.

Art
We enjoy art, and have become especially fond of the artists of the Hague School. Don has created a small website on the Hague School and edited much of the Wikipedia site on the Hague School. He has also saved a large number of copies of the works of Hague School artists at this Rijksmuseum site as well as a Powerpoint lecture he gave at La Costa Glen.


A number of years ago Don did some calligraphy. He has taken some art classes in drawing, charcoals, watercolors and pastels. Recently he has also done some Kirigami.

Hobbies
Don has worked on the Village Presbyterian Church website and the La Costa Glen website, the Carmel Valley Library website.

Elizabeth continues to sew and has done some beautiful quilts and pine needle baskets and has recently taken some beading classes.

Travel
We like to travel and visit our daughters on the East Coast. After traveling on our own in Europe a number of times, we have taken four Rick Steves tours and five Grand Circle cruises.

Fractals
In a previous life before retirement, Don taught mathematics and computer science at California State University, Los Angeles. During that time he worked on fractals and the related areas of chaos and artificial life.

Don has given some lectures on different topics at the Village Presbyterian Church : Creeds of the Church, Dead Sea Scrolls, the Reformation, and Science and Religion. At La Costa Glen he has lectured on the Hague School, Creationism, and Genetics and Politics and led some Great Courses studies on the Old Testament and the New Testament.

He has also contibuted to Wikipedia articles on the Hague School and to the Open Directory Project on the topics of Reformed Theology, Creationism and Automata Theory.
