🎁A great chemist has left us: Yitzhak Apeloig passed away on May 28, a pioneering physical organic and computational chemist. His work on reactive intermediates, strained molecules, and organosilicon chemistry became textbook knowledge.

🎁 HBT Jonathan Sessler, who turns 70 today. Best known for his work on expanded porphyrins, including texaphyrins, Sessler has shaped porphyrinoid and supramolecular chemistry for decades. A gifted teacher and mentor to over 250 PhD students and postdocs, we wish him a healthy and fruitful future.

🌻Manfred T. Reetz, an organic chemist of the highest caliber, died of cancer on April 23, 2026. Manfred Reetz, a giant of organic chemistry, will be dearly missed by his former students and colleagues as well as by the wider scientific community.

🌻The “God of Fluorine,” Karl Otto Christe, passed away on April 19, 2026, in California. Christe was most famous for the first completely chemical synthesis of elemental fluorine. He was well known as an expert in energetic materials. He received a wide range of prizes from the ACS, SFC, and GDCh.

🎁HBT to Dieter Jahn, who turns 75 today. Dieter Jahn joined BASF in 1979 and has served the scientific community in manifold ways. Since 2024, Dieter Jahn has been a member of the Advisory Board of the autobiography series “Lives in Chemistry” (l-i-c.org).

🌻Rest in peace, Günther Maier. The chemist who made one “impossible molecule” after another died on April 10 at the age of 94. He was a modest man who trained a large number of PhD students. His achievements were recognized with the Adolf von Baeyer Memorial Medal of the GDCh. l-i-c.org/1125

🌻Henning Hopf passed away on March 12 only three months after his 85th birthday. A great organic chemist who had deeply cared about our community—a true “mensch”—has left us. Lives in Chemistry l-i-c.org lost a most insightful Advisory Board member who had enormously contributed to this endeavor.

🎁HBT to Hans-Joachim Freund, who turns 75 today. Hajo Freund is not only an exceptional scientist; he also served the community in many ways—for example, as a textbook author and journal editor. He has been a great mentor whose “academic footprint” is enormous.

🎁HBT Carsten Reinhardt, who turns 60 today. His oeuvre in the history of science is vast and wide-ranging, with a focus on the history of chemistry. He has served several times as chair of the GDCh’s History of Chemistry Division, and he has been chair of the LiC Advisory Board from the beginning.

🌻A great loss: Armin de Meijere passed away at age 86 on December 17 in Göttingen. His distinguished career spanned both the golden age of physical organic chemistry & the rise of transition-metal catalysis. 250 PhD students & postdocs have lost an exceptional mentor—and chemistry has lost a giant.

🎁HBT Henning Hopf, who turns 85 today. He is an eminent hydrocarbon chemist who made major contributions to alkenes and alkines, allenes and cumulenes, as well as cyclophanes and dendralenes, and he wrote “Classics in Hydrocarbon Synthesis”, published 25 years ago by Wiley-VCH. #OrganicChemistry

🎁HBT Stephen B. H. Kent, who turns 80 today. Distance running was his passion and he also went for long distances, or rather long sequences, when it came to the synthesis of peptides and proteins, a field that his group has revolutionized through the development of “chemical ligation” methods.

🎄🔬🎨 New puzzle #AdventCalendar #ScienceArtTechAdvent—Intro Starting tomorrow, a new daily 🇩🇪 language puzzle with English subtitles about science, technology, and art will drop here every day. Post your answer in the comments and pick up some fascinating facts along the way!

🎁HBT Paul Knochel (LMU Munich), who turns 70 today—unbelievable knowing his charming boyish appeal. Developing new synthetic methods, in particular based on organometallic compounds, and applying them in the #TotalSynthesis of natural products has become a hallmark of the Knochel group.
