Continued work on Lively. Built a system of live-linked worlds in Lively, similar to Squeak 'projects', as the basis for a live designer's notebook.Implemented an 'undo' facility for Lively, and then extended its action-log mechanism to enable collaborative synchronization of multiple users. While experimenting with that same action-log mechanism, it became clear that this could be the basis of a programming-by-example on-ramp for early learners of programming.Much of this work can be viewed at https://lively-next.org/projects.html

Continued work on the Lively kernel, and demonstrated how SAP could offer improved ability for its researchers to benefit from live coding (for, eg, testing new databases and visualizations), and how its end-users might actually be able to build their own simple apps. That work significantly contributed to the move to SAP's UI5 and live browser interfaces.

Invented and developed the Lively Kernel - a self-supporting live-coding development system that runs live in any browser. It can save apps, and even new versions of itself as web pages.

Brought the Squeak system to a high level of maturity, and built an active community around it that survives to this day. Added media support such as DTP text, event and sound recorder, score and timbre editors, movie display and editing. Worked on the EToys educational environment that inspired Scratch and that is featured in the One Laptop Per Child work.

Conceived, designed and executed with the help of three others, a high-level implementation strategy for building a complete general computing environment in less than six months. The system, known as Squeak, is functional today, with support for interactive color graphics and sound. Built with a metasystem, it can be easily altered or ported to other computing platforms.

Made a good Smalltalk available on Macintoshes at an affordable price. Saved Apple from losing its Smalltalk-80 license from Xerox. Designed Fabrik, a visual programming environment in which it was possible to design simple, useful applications in less than a minute without writing any code.

I was drafted to take over this family business from my father. If it looks like another person's profile, this was definitely a separate lifetime for me.Built riding and shooting back to their former premier status. Averted a financial disaster by selling our telephone company for twice what the Directors thought we could get. Personally spoke with all employees and won against two successive union campaigns that tried to take advantage of our economic challenges. Worked with bankers and lawyers and eventually found an investor that was better qualified to manage the resort than I or any of my family. I owe the successes that we had to the warm and wonderful staff of the resort.

While Alan Kay invented Smalltalk, I was the architect and chief implementor of four generations of Smalltalk leading up to the Smalltalk-80 standard. This included an object model based on classes and messages, the Smalltalk keyword syntax, and an efficient byte coded virtual machine. I invented the BitBlt graphics operation, andimplemented it in microcode on the Alto. I gave a demo in 1974showing overlapping windows with text and graphics, and pop-up menus, which I also invented. This had an immediate effect on the STAR work at Xerox, and the gestalt of that demo can be traced through the now famous Steve Jobs demo (which Larry Tesler and I gave) to the Apple LISA and MAC, and to GUIs as we know them today.

Dropped out of PhD program at Stanford to start UDS, a company that sold a software measurement tool I designed. My father was a professor.
