Don Snyder, long time NASS member, sundial designer and conference organizer, died Nov. 21, 2022 at the age of 87. He organized two St. Louis conferences for NASS in 2008 and 2017. For the first St. Louis conference, Don worked closely with Michael Olsen of the Missouri Botanical Garden to have five sundials available for viewing, including the dedication of a dial donated by Ron Rinehard, the Schmoyer sundial made by NASS member Bill Gottesman and donated to the Garden by Don and Bill, and in the Ottoman Garden, the Ottoman Sundial designed by NASS member Roger Bailey based on the 1845 dial at Topkapi Palace, Istanbul.
At the 2017 NASS conference in St. Louis, Don organized a ring-side seat at Jefferson Barracks to watch the total solar eclipse. Don worked with Perry County and Perryville, a town on the eclipse path, to create a new sundial for the courthouse gardens in honor of the eclipsing sun. Local craftspeople then created the dial following Don's design.
Don was always available to help other sundialists, offering advice and technical assistance. He helped restore a sundial at Concordia Seminary, established a Sundial Trail of dials around St. Louis, and for a decade checked the links on the NASS website for accuracy and relevance. With his hobby of woodworking, Don made a dial for the 25th anniversary of NASS (1993-2018) that projected solar time in colors on the dial face.
Don was a senior professor in the Department of Electrical Engineering at Washington University in St. Louis. He was the Samuel C. Sachs Professor of Electrical Engineering and chair of the department from 1976 to 1986 as well as a professor of radiology at the School of Medicine. As the founding director of the Electronic Systems and Signals Research Laboratory from 1986 to 1998 he tackled imagery problems in biomedicine, astronomy and remote sensing. In the Washington University Newsletter, they noted that when the Hubble space telescope was launched and had a blurry focal plane, Don proposed a novel image reconstruction approach. A version of this sharpening algorithm has been used on all subsequent images.

What makes a sundial? Practically anything. Sasch Stephens discusses how he became interested in dialing. Since then he has turned many objects into solar time devices. It takes some creative thinking to invision how a common object can become a working sundial. One of the most recent projects turned a 54 x 28 foot south side of a building it into a giant sundial mural in association with Allied Arts and the talents of artist Gretchen Leggitt. The dial was dedicated on September 22, 2018. View his interview at https://sundials.org/index.php/videos/making-and-using-sundials
British Sundial Society Founder Christopher Daniel Passes

NASS is saddened to report the passing of one of the UK’s pre-eminent sundial designer, Christopher St. J H Daniel who died on May 17, 2022. His works are to be found all over the UK, ranging from private commissions to major public works and to restorations and reconstruction of old and damaged sundials.
After a 13-year career at sea, Christopher Daniel joined the staff of the National Maritime Museum at Greenwich in 1964, working in the Department of Navigation & Astronomy. From 1967 onwards, his early curatorial responsibilities encouraged him to make a particular study of sundials and dialing literature. Christopher designed the now well- known "dolphin" equinoctial mean-time sundial at Greenwich, celebrating the Queen’s Silver Jubilee in 1977. In 1989 he and three others founded the British Sundial Society. From 1990, Christopher served as its Chairman, and more recently as President. His expertise and artistry in sundial design will be missed.
Netherland Sundial Society Founder Passes

Frans Maes of the Netherland Sundial Society writes: "We deeply regret to inform you that Hans de Rijk, founding member in 1978 and honorary member of the Netherlands' Sundial Society, passed away on November 23, at the age of 95. He served in the Board of the Society for many years and wrote some 150 articles in its Bulletin. Among these were important contributions, such as a latitude independent sundial, and the family of equator projection dials. A more playful result of his creativity were 'postcard dials', which he used to design while waiting for his Chinese take-away dinner."
"Hans was a popularizer of mathematics and astronomy and wrote many books about these subjects, under the pseudonym Bruno Ernst. His motto was: "Nescius omnium curiosus sum", I don't know anything but I am anxious to know everything. His eagerness to learn was equalled by his striving and ability to teach. He has been a teacher of mathematics and physics, founded the mathematics magazine 'Pythagoras' and the physics magazine 'Archimedes', aimed at secondary school students. He founded the first public astronomical observatory in the Netherlands. He also founded the organization 'Ars et mathesis', where art and mathematics meet, and its magazine with the same name. He became friends with the famous Dutch artist Maurits Cornelis Escher and wrote several books about Escher's work. Later on, he wrote extensively about impossible figures."
"Planetoid 11245 bears his name.".
"We lose a generous, inspiring, modest and productive diallist and friend."

Sundial Garden Sprouts in Vancouver

He may be wheelchair bound, but that doesn't diminish Tom Laidlaw's enthusiasim for sundials. In front of his house on Carolina Lane is the Vancouver Heights neighborhood landmark - a sundial garden. And what has he planted?
There is a bright circular equatorial sundial that shows the time from 4am to 8pm (and even an offset for daylight saving time). On the grass is an analemmatic sundial sundial marking time from 6am to 6pm for anyone who wants to stand to the plywood walkway. On a table near the house are a series of globe, equatorial and horizontal sundials as well as other sundial types that he will gladly explain. For example, Tom has turned a skate board into a polar dial by adding a "T" gnomon in the middle. And then there is a model of the Jefferson dial where you swing the gnomon around a globe to cast only a thin line shadow
Katie Gillespie, of the Columbian, reports "The 80-year-old retired electrician has always been a 'do-it-yourself kind of guy,' he said. For a while, it was skateboards he fancied, and bookshelves, and a Benjamin Franklin chair that transforms from a chair into a stepladder. He’s self-taught, he said, researching new projects online, then diving in.... 'It’s fun to watch him talk to people about it,' said Debra Brouhard, Laidlaw’s daughter and neighbor."
His latest obsession is sundials. As a member of the North American Sundial Society, Tom now designs a multitude of sundials. Visitors see his yard dotted with all types of sundials. They come in all sizes: big and small. His analemmatic sundial on the lawn always draws attention. Nearby, a plumb bob dangles from a beam. allowing Tom to tell time solar noon. when the shadow draws a line on the lawn pointing due north.
Gillespie found that, "Laidlaw’s passion for sundials began in 2009, when his grandson, Doug Brouhard, stuck a stick in the ground while they were camping. Doug Brouhard was about 12 at the time, and the dial didn’t quite work, Laidlaw said. It was the right idea, though, and a new hobby was born. 'I still have the stick that started it all,' Doug Brouhard said."

Richard Mallet at Cornell Univ. Sundial
Richard Mallet, former British Sundial Society Trustee, Council Member and former BSS Webmaster passed away on Nov 7th, 2016 with funeral held on Dec 12th, 2016. He lived in Eaton Bray, UK and had many interest in physics, mathematics, and sundialing. Those of us maintaining websites know of the difficulty in perserving order, yet always allowing for expansion of new material. "After a near disaster with the [British] Sundial Society's then heavily modified and entirely non-compliant website, Richard stepped in at no charge to the Society to rewrite it using the then new Expression Web software from Microsoft. This proved very successful and was of course fully W3C compliant."
Over the next year, the North American Sundial Society website will migrate from an older version of the Joomla Content Management System to the fully maintainable Joomla 3.x version. The majority of content and organization will remain intact, but new innovations are expected.

Seattle - Sundial Capital of North America
- Details
- Hits: 15436
In the May 14, 2013 edition of The Seattle Times University of Washington professor Woody Sullivan was honored as ‘Mr. Sundial’ for his persistence in declaring Seattle as the Sundial Capital of North America. Dr. Sullivan has worked on more than a dozen dials in Seattle, including the large 20x30 foot vertical dial on southwest wall of the Physics and Astronomy building at UW and the elegant 11x17 foot reflection sundial painted on the ceiling of his garage at N 47° 41.232, W 122° 21.562. A small circular mirror outside the south facing window reflects a spot of light onto the ceiling.
The reflection sundial was a labor of love taking over 3 years to create. Woody marked over 700 locations on the ceiling that allowed him to draw the local solar time, dates, hours of daylight, solar azimuth and altitude, analemma, and even hours to dawn. And being a radio astronomer, he marked the transit sidereal time for two radio sources. The dial was painted with marvelous beauty by a local mural artist, Jim Noonan. The sundial is very personal to Woody, showing time marks for the date he married to the birthdays of himself, his wife, and two daughters. The zodiac painted along the ecliptic has a local touch, representing Pisces by a pair of sockeye; Cancer by a Dungeness crab; and Capricorn as a mountain goat. There is even a compass rose.
Fred Sawyer, president of the North American Sundial Society (NASS) is quoted by Erik Lacitis, Seattle Times staff reporter, saying “it’s likely true that Sullivan’s garage sundial is one of the best in North America.” When the NASS visited Seattle for the 2011 annual sundial conference, they visited Woody’s Reflection Dial and a marker was added to it for the date and time of itsofficial dial dedication held on Saturday 22 August 2011. “We toasted the sundial with an appropriate wine, ‘Wehlener Sonnenuhr’ by Joh. Hos. Prum, the fine Mosel Kabinett from the German vineyard with a large vertical sundial.” said Roger Bailey, the society’s secretary.
Among Dr. Sullivan’s accomplishments in the world of sundials began in the early 1990’s when the University of Washington’s Physics and Astronomy Building was being designed. He suggested a large vertical (southwest declining) sundial. The dial was completed in 1994 and Woody was hooked. He also helped design sundials used on the Mars exploration rovers Sprit and Opportunity that landed ion the Martian surface in 2004. A campaign to build sundials all around our world ensued with the motto “Two Worlds One Sun”. [photos from NASS]
