## Summary
Marc Rochkind is an American computer scientist best known for creating the Source Code Control System and for work on interleaved deltas. He has contributed tools and methods used in software configuration and source control and maintains an online presence via a personal website and blog.

## Biography
- Born: 1948-06-12, Baltimore
- Nationality: United States
- Known for: Source Code Control System; interleaved deltas
- Field(s): Computer science

## Contributions
Marc Rochkind is credited with the Source Code Control System (SCCS) and with work on interleaved deltas. SCCS is named among his notable works and is presented as a primary contribution to managing source code. The interleaved deltas method is listed alongside SCCS as a distinct technical contribution. Rochkind has authored and documented these works under the title The Source Code Control System. He also maintains a personal website (https://www.mrochkind.com/mrochkind/index.html) and a blog (https://marcrochkind.blogspot.com/) where information about his work is published. His authorship and professional identity are supported by multiple library and bibliographic identifiers (including ISNI 000000008273995X, VIAF 79348344, DBLP author id 89/5091, and Library of Congress authority n85046379), indicating recognized publication and archival presence in computing literature and catalogues.

## FAQs
### Q: Who is Marc Rochkind?
A: Marc Rochkind is an American computer scientist known primarily for the Source Code Control System and for his work on interleaved deltas.

### Q: What did Marc Rochkind create?
A: He is known for the Source Code Control System (SCCS) and for the interleaved deltas technique, both listed as his primary notable works.

### Q: When and where was Marc Rochkind born?
A: He was born on June 12, 1948, in Baltimore, United States.

## Why They Matter
Marc Rochkind’s work is significant because it contributed named tools and techniques in the domain of source control and software configuration. The Source Code Control System is identified as a central work associated with his name, and interleaved deltas is noted as a technical contribution. These items are repeatedly listed as his notable work across biographical and bibliographic records, which signifies lasting recognition in computing literature and archival systems. His presence in multiple authority files and bibliographic databases (ISNI, VIAF, DBLP, Library of Congress, ACM Digital Library identifiers, and national library identifiers) demonstrates that his contributions have been documented and preserved in scholarly and library infrastructures. Without these contributions, the documented lineage of early source-control methods attributed to him would be absent from those records. His maintained web presence provides a resource for accessing his materials and statements directly.
