Welcome to the start of another year with Seminars in Thrombosis and Hemostasis (STH), this being my 16th year anniversary as Editor in Chief, so still a teenager! In contrast, 2024 marks the 50th birthday of STH, which first published in 1974. 1 A half century of publishing is a landmark worthy of celebration. We started the celebrations in 2022, when we published our first Celebratory issue. 2 A second Celebratory issue was published in 2023. 3 Both issues were rich with content of a historical nature related to the fields of thrombosis and hemostasis. The current issue represents the third in the series of historical papers. We plan to prepare a fourth and final compilation later in this year.As now standard for these "welcome" editorials, I will again sincerely thank all past and current contributors to STH over the many years, as well as to all past, current, and future Guest Editors who commit their time to advance STH, and of course the current and past Editorial teams. There has been no major overhaul of the general editorial team at the time of writing, although some adjustments will continue to occur over the coming years. However, in 2024, we do bid farewell to some of our senior editors. Professor Hau Kwaan has decided to retire from STH, after 10 years as a Senior Editor. Professor Kwaan first contributed to STH in 1979, 4 just a few years after STH began publishing, and so representing 45 years of association with this journal-a much longer tenure than my own. Also departing as Senior Editors are Anne Mett Hvas and Ton Lisman.
