Lars Jaeger (born 1969 in Heidelberg, Germany) is a Swiss-German author, entrepreneur, financial theorist, and alternative investment manager. He writes on the history and philosophy of science, technology, and has in the past been an author on hedge funds, quantitative investing, and risk management. In his widely read blog as well as other media he frequently writes on issues concerning scientific developments, new technologies, and their meaning for society. He is the author of many books on various topics. In 2014, Jaeger published a universal history of science (in German), and in September 2016 a book on the interplay of science and spirituality (again in German). His next book “Supermacht Wissenschaften” (“Superpower Science”, 2017, again in German) outlines scenarios of mankind’s technological future. His 2018 book “The Second Quantum Revolution – From Entanglement to Quantum Computing and Other Super-Technologies” (2018, English as well as German editions) deals with the latest quantum technologies. His 2019 book “Mehr Zukunft wagen” (Daring more future”, 2019, in German) is a confrontation with the impending technological upheavals that lead to what Jaeger calls “The Human Crisis”. In 2020 he published “Sternstunden der Wissenschaft. A Success Story of Thinking” (in German) in which he describes the triumph of science on the basis of four essential intellectual virtues. His 2021 book “Ways Out of the Climate Catastrophe – Ingredients for a Sustainable Energy and Climate Policy” provides an outlook on a possible climate-friendly economy of the future. In 2022 Jaeger published two books: 1. “Emmy Noether – Her rocky Path to the topf of Mathematics” (in German) and 2. “The Stumbling Progress of 20th Century Science – How Crises and Great Minds Have Shaped Our Modern World”. The first gives a biography – readable also for non-mathematicians – of the greatest female mathematician in history. The second books describes the revolutionary development of ALL sciences from around 1880 to 1950.
Jaeger has for many years been an influential voice in the hedge fund industry on fostering developments towards more transparency, liquidity, and cost efficiency. He is the founder and CEO of Alternative Beta Partners AG and currently serves GAM as Head of Alternative Risk Premia.
Prior to founding Alternative Beta Partners in early 2010 Jaeger had served Partners Group as a partner for eight years. He is a co-founder of saisGroup, a hedge funds asset management firm, which merged into Partners Group in 2001. Jaeger started his finance career in 1997 at the quantitative research firm Olsen & Associates in Zurich. Before he studied physics and philosophy at the University of Bonn in Germany and École Polytechnique in Paris and holds a doctorate degree in theoretical physics from the Max Planck Institute for the Physics of Complex Systems in Dresden, where he also performed post-doctoral studies in the field of non-linear dynamics.
Commentaries on hedge funds
Jaeger frequently comments in print, online, and on television on financial issues, particularly around hedge funds, their return sources and risk management for alternative investment strategies.
He has been an early public advocate for independent risk management, transparency, and cost reduction for hedge funds   having designed and run one of the first managed account platforms for these historically rather opaque investment structures in 2000. In 2003, based on his investment experience as well as his academic research on hedge funds return sources, he (jointly with Bill Fung and David Hsieh) coined the term alternative beta  identifying this as the most important component of hedge fund returns (increasingly referred to “alternative risk premia” today). The research by Jaeger  initiated an industry wide discussion on the return attributes (and cost features) of hedge funds which starting in 2007 led to the appearance of hedge funds replication products and more recently to the growth of the “alternative risk premia” industry into a major investment topic of the global asset management industry.
Jaeger is author of several research articles in leading academic journals. He received the Martello award “best paper of the year” by the Journal of Alternative Investment in 2005 for his influential and much cited paper “Factor Modeling and Benchmarking of Hedge Funds: Can passive investments in hedge funds strategies deliver?”.
Writing about the history and philosophy of science and technology
In September 2014 Jaeger published “Die Naturwissenschaften – Eine Biographie” with Springer Spektrum, a book which aims at outlining the history of science from its origins to today for a broad range of readers from little scientific background to scientific expertise in a clear and comprehensible way. His second book “Wissenschaft und Spiritualität” was published in September 2016. Here Jaeger discusses the interplay of science and spirituality. In his third book “Superpower Science – Our future between heaven and hell” (2017) Lars Jaeger outlines a journey into our immediate technological future. His 2018 book “The Second Quantum Revolution: From Entanglement to Quantum Computing and Other Super-Technologies” provides insights into developments and possibilities of the latest quantum technologies. His 2019 book “Mehr Zukunft wagen” (Daring more future”, 2019, in German) is a confrontation with the impending technological upheavals that lead to what Jaeger calls “The Human Crisis”. His 2020 book “Sternstunden der Wissenschaft. Eine Erfolgsgeschichte des Denkens” (Decisive moments of science – A success story of hums thinking) describes the origin of science on the basis of four essential intellectual virtues that make up our thinking and which must be defended, especially in times of “fake news”.. His 2021 book “Ways Out of the Climate Catastrophe – Ingredients for a Sustainable Energy and Climate Policy” provides an entertaining presentation of the essential issues of energy policy and their impact. His two 2022 books are: 1. “The Stumbling Progress of 20th Century Science – How Crises and Great Minds Have Shaped Our Modern World”  describes the revolutionary development of ALL sciences from around 1880 to 1950, and 2. “Emmy Noether – Her rocky Path to the topf of Mathematics” (in German)”. gives a biography – readable also for non-mathematicians – of the greatest female mathematician in history.
On his web page Jaeger publishes a bi-weekly blog on matters of science, technology, philosophy, and spirituality. He also blogs regularly on the German platform scilogs.de.
