Alisdair Meredith

Alisdair Meredith is a software developer at BloombergLP in New York, and previous chair of the C++ Standard Committee Library Working Group.

He has been an active member of the C++ committee for just over a decade, and by a lucky co-incidence his first meeting was the kick-off meeting for the project that would become C++11, and also fixed the contents of the original library TR.

He is currently working on the BDE project, BloombergLP’s open source libraries that offer a foundation for C++ development, including a standard library implementation supporting the polymorphic allocator model proposed for standardization.

Andreas Fertig

Andreas is a freelance trainer and consultant for C++ specializing in embedded systems. Since his computer science studies in Karlsruhe, he has dealt with embedded systems and the associated requirements and peculiarities. He worked for about 10 years for Philips Medizin Systeme GmbH as a C++ software developer and architect with focus on embedded systems.

He also develops macOS applications and is the author of

Bob Steagall has been working in C++ since discovering the second edition of "The C++ Programming Language" in a college bookstore in 1992. The majority of his career has been spent in medical imaging, where he led teams building applications for functional MRI and CT-based cardiac visualization. After a brief detour through the worlds of DNS and analytics, he’s now working in the area of distributed stream processing. He is a voting member of the C++ Standardization Committee, and has a blog where he occasionally writes about C++ and related topics. Bob holds BS and MS degrees in Physics, is an avid cyclist when weather permits, lives in fear of his wife’s cats.

Garth is the Head of Learning at Instil. He gave up full time development back in 1999 to first teach C++ to C coders, then Java to C++ coders, then C# to Java coders and now teaches everything to everybody, but prefers to work in Kotlin. If he counted deliveries it would have gone past 1000 some time ago. He is the author of over twenty courses, speaks frequently at meetups, presents at conferences and co-organises the Belfast BASH series of developer events. When not at the whiteboard he coaches Krav Maga, lifts heavy weights and fights nerf wars with his kids.

Jamie Allsop

Jamie is a long time C++ developer who started out with C++Builder, and even wrote an international bestseller on it almost 20 years ago! He has spent many years developing software for highly constrained environments, first as an audio engineer for companies like DTS but now spends what coding time he has writing code in the ultra low latency finance domain.

A speaker at conferences around the world for many years he often gives talks on agile development and organisational theory, particularly as it relates to distributed and dispersed teams; software architecture, particularly as it relates to constrained environments such as finance and low latency; and also tooling, both agile, build tools, and then any stuff in between.

A long time member of the BSI C++ committee, C++ is his language of choice but like many he enjoys some Python too. Originally an electrical engineer by training he holds a PhD in Adaptive Framework Design for High Performance Systems and has continually sought ways to bring that interest and learning into his code bases. Currently CEO of he is focused on developing new technology in the low latency exchange, crypto and AI space, all using C++ of course…​

Nevin ":-)" Liber

Nevin ":-)" Liber is a computer scientist at Argonne National Laboratory, a C++ Committee member and a veteran C++ developer. He first discovered the language over three decades ago while at Bell Labs when a friend called and asked, “What do you know about C++? You folks invented it!”

His professional career has taken him across various industries and platforms: big data, low-latency, operating systems, embedded systems, telephony and now exascale computing, just to name a few. He spends much of his time pushing his peers, colleagues and friends (and just about anybody else willing to listen) to use modern C++ constructs along the way.

Looking to learn more about the language, he got involved with the C++ Committee and hosted (with the generosity of his employer at the time) both the C++ and C Standards meetings in Chicago. These days he frequently finds himself in the middle of the debates involving the more contentious parts of the Standard Library.

With broad experience in industry, academia, consulting, and research, Dr. Walter E. Brown has been a C++ programmer for over thirty-five years, joining the C++ standards effort in 2000. Among numerous other contributions, he is responsible for introducing such now-standard C++ library features as cbegin/cend, common_type, gcd, and void_t, as well as headers <random> and <ratio>. He has also significantly impacted such core language features as alias templates, contextual conversions, variable templates, and static_assert. He conceived and served as project editor for the International Standard on Mathematical Special Functions in C++, now part of C++17.When not playing with his grandchildren, Dr. Brown is an Emeritus participant in the C++ standards process, with several more core and library proposals under consideration.
