Slide 4-11: Blood Evidence Timeline (16th Century - 1960)
- 1628 - William Harvey: Blood circulation theory, crucial to understanding blood’s role in evidence.
- 1853 - James Marsh: Developed a method to detect arsenic in blood.
- 1863 - Jean Servais Stas: Introduced a method to identify human blood.
- 1901 - Karl Landsteiner: Discovered blood groups (A, B, AB, O), essential for blood typing.
- 1932 - Dr. Alfred B. Sweeney: Advanced techniques in blood typing and analysis.
- 1947 - Dr. Paul L. Kirk: Developed blood spatter analysis for crime scene investigation.
- 1955 - Dr. Leon Lattes: Developed a method to identify blood types from dried stains.
- 1959 - Robert E. Jones: Work on the properties of blood evidence began leading to modern techniques.
Slide 12-19: Fingerprinting Timeline (16th Century - 1960)
- 1892 - Sir Francis Galton: Published "Fingerprints," establishing the uniqueness of ridge patterns.
- 1901 - Alphonse Bertillon: Introduced anthropometry but later acknowledged the importance of fingerprints.
- 1905 - Edward Henry: Developed the first fingerprint classification system.
- 1908 - Harry Jackson: Convicted using fingerprint evidence in the U.S.
- 1911 - U.S. Courts Recognize Fingerprints: Landmark case in criminal identification.
- 1915 - FBI’s Use of Fingerprints: First comprehensive fingerprint database established.
- 1920 - Juan Vucetich: Established a police agency in Argentina and initiated fingerprint use in south America.
- 1950s - Advances in photography and ink technology improve fingerprinting processes significantly.
Slide 20-27: Ballistics Timeline (16th Century - 1960)
- 1514 - Leonardo da Vinci: Studies of projectiles and their motion.
- 1793 - S. A. Kinsey: Developed methods for examining fire arms and bullets.
- 1854 - Forensic Ballistics Recognized: Insight into matching bullets to firearms.
- 1889 - Hiram Maxim: Advanced automatic weaponry and contributed to ballistics study.
- 1900s - Development of rifling and how it affects bullet trajectories.
- 1925 - Calibre Weights: Adoption of standardized measures aids in forensic analysis.
- 1935 - Development of comparison microscopes for analyzing bullet markings.
- 1950s - Biomechanical studies aid in movement prediction of projectiles in forensics.
Slide 28-30: Foundational Events Outside Forensics
-
Blood Evidence:
- Microscope (Invention): In 1590, Zacharias Janssen invents the compound microscope, essential for examining blood cells.
-
Fingerprinting:
- Photographic Camera (Invention): Early 19th century invention, led to improvements in capturing and analyzing fingerprints.
-
Ballistics:
- Gunpowder (Invention): Developed in the 9th century, it revolutionized weaponry and necessitated the scientific study of bullets and trajectories.
Slide 31: Summary & Conclusion
- Recap of Key Developments
- Briefly summarize the importance of the advances covered in blood evidence, fingerprinting, and ballistics.
- Impact on Forensic Science Today
- Discuss how these developments shaped modern forensic investigation and legal proceedings.
Slide 32: References
- Cite all sources used to gather information for the project, including textbooks, websites, and academic papers.
Additional Presentation Tips:
- Visuals: Use images, charts, and diagrams to enhance understanding. Consider audio or video clips where appropriate.
- Engagement: Prepare to discuss each slide and invite questions for deeper discussion during the presentation.
- Keep Text Minimal: Use bullet points and ensure your narration fills in the details verbally.
This structure creates a comprehensive and engaging project that effectively communicates the historical progression of physical evidence methodologies in forensic science.
