Editorial: Special Issue for the 75th Anniversary of the IEEE Circuits and Systems Society [Editorial]

IEEE Circuits and Systems (CAS) Society (CASS) celebrates the 75th Anniversary of the Society in 2024. This is a major celebration for CASS after the Golden Jubilee celebration in 1999. This special Issue of the IEEE Circuits and Systems Magazine is one of many celebrations and events planned this year by and for CASS members. The Celebrations not only reflect upon the history of our Society from multiple angles but also look forward to the future. The planning for this Special Issue started in July 2023 when Gabriele Manganaro, VP-Publications of IEEE CASS, tasked the incoming Editor-in-Chief (KP) to plan for the Special Issue. A Call for White Papers was issued to the CASS membership on 20 July 2023. The authors were asked to provide historical progress over the last 25 years and point out future directions for the next 25 years. We received numerous White Papers in September 2023, and were able to invite only few authors to submit Full Papers. Authors of Invited White Papers submitted their Full papers in second half of December 2023. All reviews were completed by March 2024. Before providing an overview of the papers in this Special Issue, we begin by thanking all the authors who took the time to submit the White Papers (whether Invited or not) and the Full papers. We are very grateful to all the reviewers who provided reviews in short notice due to the time constraints to publish the Special Issue.
