The fields of instructional design, learning & development and learning theory have been shaped by a wide range of people over many years. We decided to study these influences, to get an idea about just how wide-ranging the sources of influence are. In this post, we share a list of 100 people who are some of the most influential people within instructional design, learning and development, and learning theory. We have decided to call this list the "Top Learning Influencers".
Our list was carefully curated through extensive research and input from hundreds of experts in the field. We surveyed industry leaders, asked for recommendations from top professionals, and analyzed the networks of influence within the field to identify 100 individuals who have been instrumental to getting the industry to where it is today. We believe that recognizing and showcasing the achievements of these individuals will not only highlight the important contributions they have made to the field, but also inspire others to continue pushing the boundaries and advancing the industry as a whole.
The final list is a testament to the hard work, dedication, and innovation of these individuals, and we are proud to recognize their achievements. We hope that recognizing the achievements of these individuals is important not only for their own careers, but also for the field as a whole. By showcasing their contributions and highlighting the important work they are doing, we hope to inspire others to continue pushing the boundaries and advancing the industry.
Below is the list, and at the bottom of the post is some information about how we constructed it.
The following list is in random order.
We are announcing the winners from the 3rd of January 2023 to the 24th of February. We plan to announce between 15 and 20 people per week. To see the announcements and stay up to date, follow David Kofoed Wind and Eduflow on LinkedIn.

How did we construct this list?
In order to find the most influential people, we talked to hundreds of people within instructional design and L&D. We asked them to name the people who had influenced them the most. We then reached out to the people who were mentioned as influencers, and in turn asked them who they have been influenced by. This way, we built a network of influence. We collected recommendations from more than 177 people and in total collected 799 recommendations (so around 4.5 recommendations per recommender).
As an example, William Cronje from our team has drawn influence from Guy Wallace, who in turn has been influenced by Jane Bozarth (among others). With this network, we could then map out the most influential people. We analyzed who were mentioned as an influence often, but also who influenced the influential people. So if many of the influential people were influenced by the same person, then that person has influenced the whole industry even more. In order to rank people by their "network influence", we used the PageRank algorithm developed by Google to assess importance of websites - they realized that websites were important if other important websites linked to them.
Based on this analysis, we have selected the 100 people who have had the most influence on the industry. They are the people listed here.
As with any piece of research, there are of course limitations to the methods we used. Here we have tried to list some of them.
- When building a network of influence, we are for good reasons not able to talk to people who are dead. Consequently we don't get to see who influenced some of the original thinkers. One way to address this in a future update would be to use their academic citations (when available) to determine which other researchers they were inspired by.
- Given that the fields are broad and overlapping, people chose different strategies for who to recommend. Some people went back to the original thinkers (like Socrates), and some people said that their biggest inspiration was one of their current colleagues. Similarly, some people were inspired by people within their own field, and some people drew their inspiration from outside of their own field. As a consequence, the influence network contains recommendations of different types. We decided to treat them all in the same way to get as much data as possible. This also allows us to illustrate the complex network of influence that exists.
- While the PageRank is excellent in design, it does come with some arbitrary results. What is better - getting recommended by three people, or getting a recommendation by a top influencer? We used the default parameters of PageRank as recommended by Google in order to create our list - but of course changing parameters could change the order. That being said, most of the top 100 list was quite stable under different parameters.
