Many people are asking about who is who in that picture from my phone back on Ethereum's launch day. So here we go with what I remember. Starting from Vitalik and going clockwise. Vitalik - @VitalikButerin Gustav Simonsson - worked with us a bit and then went on to Dfinity Christian - creator of solidity @ethchris Liana Husikyan - solidity and main dev of remix @LianaHusikyan Christoph Jentsch - EF testing suite, founder of slockit, creator of the DAO, now corpus ventures @ChrJentzsch Gavin Wood - ethereum founder, polkadot founder @gavofyork Vlad Gluchowski - Worked in whisper. I think he is also @gluk64 's brother. Kelley Becker - Was just hired as chief operating officer. Did not stay long Vlad Zamfir - EF research. Casper and more. Still doing research on the field: @vladzamfir Felix Lange- Go ethereum developer. Emacs user (❤️ ). Still with us (fjl in github) Frithjof Weinert - Hired at the time as CFO for the foundation (?). Fabian Vogelsteller - @feindura. Developer mainly focused on web3.js and mist. Now founder of @lukso_io Aeron Buchanan - Was doing OP stuff for the EthDEV UG. Later went on to work with Gavin in parity. A very nice guy. Lefteris Karapetsas - That's me. I worked on Solidity compiler and the c++ client at the time. Jutta Steiner - Worked at the EthDEV UG in various positions, mostly testing and preparing the audits if I recall. She later went on to parity with Gavin. @jutta_steiner Yann Levreau - @Yann300 Worked on remix and is still part of the same team.
