About Herb Dengler

For many, Herb Dengler was a link to the time before the dawn of Silicon Valley, when people marked their travel by the shape of the hills, not by freeway signs. A true native, he spent his ninety years walking the Santa Cruz Mountains, particularly Jasper Ridge and Portola Valley, coming to know all its inhabitants–butterflies, fishes, birds, trees, flowers, and people. He loved sharing his knowledge with family, friends, Stanford students, Jasper Ridge docents and visitors. He persistently sought to protect the wildlands while leaving a place for people within it. 

He taught the first class of Jasper Ridge docents, helped found the Portola Valley Conservation Committee, and built many trails throughout the area, allowing easy access to the beauty around us. In 1997, the Palo Alto Senior Coordinating Council honored him as having lived a "Lifetime of Achievement." In 1999, he was the honoree at Portola Valley's annual celebration of community and open space, "Blues and Barbecue." 

Herb's other great love was art. From an early age, he drew and painted butterflies, fish, birds, and wildflowers. This was during an era when biologists were expected to be competent artists. For many decades, Herb ran a framing and art gallery in Burlingame, later in Palo Alto. He was a well-known restorer of paintings and an expert in Western art. 

Herb combined these two great loves in his home and in his own art and writings. For more than fifty years, he and his family lived among the redwoods along Sausal Creek in Portola Valley in a house full of beautiful paintings and prints. His articles and drawings on natural and local history were published in local papers, the Stanford magazine and Peninsula Open Space Trust's Landscapes.
