Artist Guest Jeff Lee Johnson

I grew up in rural Minnesota far enough from town and friends to have nothing else to do but read and draw. Luckily, my mom could draw and paint as well, and provided me with an endless supply of materials, tools and patient instruction. We had a house filled with books by authors like Edgar Rice Burroughs, Kenneth Robeson, Isaac Asimov, Robert Heinlein and Arthur C. Clark, and the stories and art left a deep impression on me.
Following that childhood, I dedicated both time and money at Moorhead State College and The University of Minnesota to learning quite a bit more about art. The idea of making a living doing art, however, did not comport with the reality that I had come to know, so I left school to travel the world, do odd jobs, wait tables, and ultimately, build houses.
Fast forward 20 years, to the time when my carpenter career had taken its toll on my knees and elbows. I woke up one morning and decided it was time to finally try to make a living doing art. I simultaneously discovered the world of digital illustration and the world wide web, put two and two together, and decided to take the leap. With the tireless support and encouragement of my wonderful wife, I began plying my craft professionally in 2000. My first jobs were in commercial illustration but my real love was sci fi, fantasy , and horror, and after a bit was able to build a career painting in those wonderful genres. I now split my energies between personal projects and art directing for the wonderful folks at Fantasy Flight Games, where I am currently Senior Art Director.
I am six illustrations into a series of images I have titled “Dark Reflections” that pay homage to my love for distant times, places, people, and events. In them I balance a deep strain of heartfelt nostalgia and optimism with a slightly devious inclination to subvert expectations. We all have a dash of mayhem in us, and shadows almost always have monsters lurking in them (at least in our minds.) It’s not possible for me to witness a charming scene without seeing through to a possibly sinister hidden narrative, which always tickles me, and this series is probably as close to my personality and worldview as can be. I am delighted that it has a worldwide fan base, and am amused to note there is at least one print of my work on all seven continents (including Antarctica). Anyone know someone in NASA? The space station is my next target 😉

Toastmaster Tadao Tomomatsu
Parts Made in Japan-Assembly in the USA
A WORK OF SCIENCE FICTION/Fantasy/Etc.?
Long ago, no no not that far away. An Origin Story?
Tadao was manufactured with parts from Japan and Assembly in the U.S.A.. the confusing part was the Apple OS in a PC system.. or was that the other way around?
Not so typically: Father- Renaissance Scientist of the ages; Mother- Professor of Japanese/Culture/Professional Translator.
And that all blew up when the family in Japan took pity and sent Japanese toys before they became worldwide wonders.
Fascinated by Giant robots, Science Ninja’s super equipment fighting the aliens.
And growing up a bit of a TV head: Watching PBS, Dr.Who, Danny Kaye and John Wayne didn’t help. May have confused people more in schools when the southern accent would pop out. Or British… followed by Scottish… (don’t ask).
And theater was a downfall… or was it being a Radio DJ in Chicago that no one knew about? “A great face for radio..”
Then California bound: Actor, Singer, dancer(sometimes) Stunts-various. Entertainer, MC, Impersonator, Props, sets, even a period of Director, Writer, Producer even a Comedian with weekly times at the Laugh Factory and the Comedy store back in the day.
With some of the strangest stories- ask sometime about:
How he was not Japanese enough for the movie Pearl Harbor. ONE of MANY… le sigh.
Some of the highlights in Hollyweird:
Mr.Shake-Hands Man – USA/2: For the British/American TV Show “BANZAI”. A game show of various segments. Mr. Shake-Hands Man would shake hands with celebs on the Red Carpet and how long would he shake hands. You had to guess.
Maybe even a Baby Septuplet on the Tonight Show.
A bewildered tourist in Inspector Gadget.
NYPD Translator in “HEROES” and yes oddly with the Speaking roles. Makes him BOTH a DC And Marvel Character and you can find his profile in the HEROES graphic novel.
And the least recognized. Was on CyberRadioTV.com. The world’s first 24hr. Internet “Radio” station. Groundbreaking and innovation provided and IDEAS from Tadao. Which was kind of a base for all other internet shows to eventually things like You Tube and other online productions.
Alas Not much credit.
ON the Fannish side was a Con-Chair for Loscon in LA. Even relaxacons for LASFS. MC, Toastmaster, Auctioneer. Host or even Booth babe (it’s for Worldcon in Anaheim in 2026).
Working at Gallifrey One (yarp Dr.Who). and a “Guardian of the TARDIS”. They were never clear Tho if it was the White or Black Guardian. Wait? Wrong show?? Um..
Or even working Labyrinth of Jarreth Masquerade (LOJ). Either, onstage with the vaudeville stylings of the Goblins. To Small Crafty service for the rest of the actors er I mean Elves, Sypher Royals, Mermaids, Elementals or even a Dragon or three.. or am I patching up the Knights? The Attendees?? Er never mind.
Mostly retired from Acting.
He has taken over his father’s works. As Dr. Hideo Tomomatsu and Prof. Yuko Tomomatsu had many scientific works since their passings.
So now very Science Adjacent.
Happily finds Des Moines to be one of his Home Conventions and happy to have some family time.
And Thanks everyone for their time, efforts, support for putting up with me or at least keeping science fiction and fantasy alive and well.. 😊

Annie ‘Sirkles’ Drahos
The artwork created by Annie ‘Sirkles’ Drahos may look like a bunch of abstract circles, but the designs are actually the words and letters of an intricate circular script. This script started in 2011 when her friend, Loren Sherman, released the first ever widely used fan-made variation ‘Circular Gallifreyan.’ Not long after, she was listed on Loren’s site as the recommended artist for custom designs. Since that time, she has remained active in the script’s development and growth. As the popularity of the script continued to grow, it eventually made its way on screens in BBC’s very popular show: Doctor who. This, naturally, resulted in a huge boost to Annie’s career as a full time scribe. With thousands of hours, over a decade of experience, and several hundred designs under her belt, she comfortably boasts to be the “most experienced scribe of the only fan made script to have ever appeared on Doctor Who.”

DemiCon Hall of Fame
At DemiCon 15 we wanted a way to extend special acknowledgement those who have helped make DemiCon what is today. The DemiCon Hall of Fame was created to recognize those particularly influential individuals.
Rusty “James” Hevelin

At DemiCon 15, Rusty Hevelin was our first inductee to DemiCon Hall of Fame. Rusty had started as our Fan Guest of Honor at DC 1, but somewhere before our first convention came around, he was named Toastmaster. From that day forth, he was our Toastmaster. When Rusty became a member of the DemiCon Hall of Fame, he was given the title of Toastmaster Emeritus, but he did not rest on his laurels and has been at every DemiCon until DC22 when health problems kept him away. Rusty passed away in 2011.
To learn more about Rusty, follow this link to the Hevelin Collection at the University of Iowa.
Joe and Gay Haldeman

Gay and Joe had an intricate part in growing the love of science fiction in those who created DemiCon when they were members of Science Fiction League of Iowa Students (which Joe created) and running ICON.

Joe Haldeman is a multiple Hugo and Nebula award winning author. For his spectacular career in writing science fiction and fantasy, he was given the honor of SFWA Grand Master. Joe has been our Author GOH for DC 2 and DC 20 where the Haldemans were inducted into the DemiCon Hall of Fame.

Glen Cook

Glen was made a member at DemiCon 25. Glen Cook Author guest of honor for DemiCon 5, known for his stellar The Black Company military fantasy series and so much more, told DemiCon this: I was born and am still under foot. Hit the ground in NYC in 1944, lived there, Indiana, and California growing up. Served in the Navy, attended U of Missouri, worked for General Motors and retired therefrom. Began writing with intent to commit publication late 1960s and have since produced 51 published books (#51, Working God’s Mischief, will come out between now and the convention), some short fiction, some articles and some essays. I have three sons, an Army officer, an architect, and a symphony musician, plus numerous grandchildren, all but one of whom seem determined to be female. And I have an amazing wife who has been with me for almost 45 years. These days I am, extremely slowly, working on expanding the Black Company chronicles by two novels and a story collection. I have become a victim of Ambition Deficit Disorder, which is what has put the slow in slowly.
Glen has been at almost every DemiCon selling books to all who love the joy of reading. Signing his and making DemiCon even more special. Thanks Glen.
