Jason Grieves
Program Manager Lead, Apple

A graduate of Virginia Tech with a Bachelor’s degree in Computer Engineering, Jason is a software engineer who has worked at Apple, Microsoft, and IBM, and is the holder of eleven patents. He is passionate about creating empowering solutions to bridge the digital divide for people with disabilities. As a successful inventor and an AAAS-Lemelson Invention Ambassador, Jason uses his platform to amplify messages of inclusion. Born with an uncorrectable optic nerve defect that impairs his vision, he now works on software that focuses on accessibility and inclusive design. 

As a child, Jason discovered that he had a gift for solving problems and for helping people. In high school, he spent one summer preparing a kindergarten teacher and classroom for an incoming student who had a visual impairment similar to his. Jason credits his father, a civil engineer, for his knack for problem-solving. As his problem-solving prowess progressed, he became more and more committed to the concept of inclusive design. 

Currently working on machine learning solutions at Apple, Jason continues to be driven in his work by empathy. He emphasizes the importance of inventing and designing with all users in mind and seeking diverse input all along the way.

Ted Henter
Formerly Founder and President of Henter-Joyce (developers of Jaws), retired

Ted was born and raised in the Panama Canal Zone, graduated from the University of Florida with a BSME, pursued a career in motorcycle racing scoring as high as 8th place in the 1978 World Championship.  He was blinded in a car accident in England later that same year, 1978.  He went back to college to learn programming, got a guide dog, and went to work at a hotel with a talking “terminal” that would only spell, not talk with whole words.

Along the way Ted met Deane Blazie and went to work for him developing talking software for MS-DOS, Deane’s company had problems, Ted was laid-off, then met Bill Joyce and they started Henter-Joyce, the developers of Jaws.

Ted loved to compete, he won 4 gold medals in the 1991 International Championship for disabled water skiers,  raced through the Panama Canal 13 times in a dug-out canoe, and learned to snow ski.  He has a brown belt in Kung Fu martial arts. Before being blinded Ted married his high school girlfriend Mel, they now had 3 adult daughters and live in St. Petersburg, FL.

Theo Holroyd
The Stephen Perse Foundation Senior School

My name is Theo Holroyd and I am 15. I come from near Cambridge in England.

I have always been very interested in technology (and learnt to touch-type in kindergarten)..

I got into coding when I was invited to spend several years helping to design a new physical way to teach blind children to code, now known as Code Jumper.

After that I got into Python when my class were doing Scratch which was inaccessible and my QTVI took me out and taught me the basics of Python.

As I already knew the basic logic of how coding worked, learning Python made more sense than it would have done otherwise.

Since then, my mentor Tim and I have done various coding projects using several different languages including Python, HTML, JavaScript and Swift.

In Python I have done several projects including a Hangman game which I started work on many years ago and have gradually made improvements to over time.

I have found coding really practically useful too as it enabled me to code a website for the Tactile Times (a newspaper I run with two other young braillists) in HTML and you can find it at tactiletimes.org

As well of my love of technology, I also love sports (favourites right now are skiing, blind tennis, running, cycling and rowing), playing the violin and hanging out with my buddy dog Penny.

Ken Perry
Senior Software Engineer, American Printing House for the Blind

Ken Perry has been working in Access Technology for 30 years and has been coding for longer. Ken began coding in 7th grade when he got his first computer, a Commadore Vic-20. Ken joined the Air Force right out of High school following his fathers’ footsteps as an Electronics tech, until fate redirected his steps into retirement. With his newfound vision on life, Ken returned to college and earned a bachelor’s in software engineering.

During his college times and after Ken worked as a self-employed Programmer on an online game system, a volunteer facilitator for the Victoria Accessible technology user group, an instructor of Microsoft Office at the Reger group, and an accessible technology consultant for the Salt Lake Community College, as well as for the Victoria Disability Resource Center.

For the last 13 years, Perry has worked at the American Printing House for the Blind. He has led multiple development projects including accessible Snap Circuits sets, accessible coding learning tools, Graphiti, Orbit Reader 20, Orion TI-84 Plus Talking Graphing Calculator (the first handheld Graphing calculator for the blind), the Orion TI-30XS MultiView Talking Graphing Calculator, the Braille Plus 18 (the world’s first accessible Android smart phone/tablet with integrated braille display and keyboard), and much more.

Until just recently, Ken has worked as the president of the local group of Blinded Veterans and continues to volunteer as a programming tutor online for blinded students that are looking for help getting started. He also continues to run an online game called Valhalla that he has run for the last 27 years and gets involved in as many Open-Source projects as he can to help with accessibility.

Braeden is 14 years old and lives near Louisville, KY. He is a five-time National Braille Challenge finalist and has a black belt in Tae Kwon Do. Braeden has been interested in coding from a very young age. Noting a lack of accessible computer games, he dreamed of learning to create the games he imagined and making them accessible for everyone. In 2020, he was given the opportunity to meet via Zoom with several computer programmers at the American Printing House. After going through the Code Jumper curriculum, he started learning Python via zoom meetings with one of those programmers, Ken Perry. He has since created several programs, including a silly little game called Plumber’s Problems and a basic server and client chat program. He also taught himself basic HTML and is a beta tester for the Code Jumper puzzle add-ons. In his spare time, Braeden enjoys playing audio games, coding, fishing, and spending time with his brother.
