To determine which psychoanalyst recognized stages of development across the lifespan, we can analyze the contributions of each individual in the provided choices.

1. **Erik Erikson**: He is known for his theory of psychosocial development, which outlines eight stages that individuals pass through over their lifetime, each characterized by a specific conflict that acts as a turning point in development.

2. **Jean Piaget**: He focused on cognitive development in children and proposed a series of stages (sensorimotor, preoperational, concrete operational, and formal operational) but primarily concentrated on childhood rather than the entire lifespan.

3. **Sigmund Freud**: Freud developed a theory based on psychosexual stages of development, which are limited in scope to early childhood and do not cover the entire lifespan in the same way as Erikson's theory.

4. **Lawrence Kohlberg**: He is known for his theory of moral development, which involves stages of moral reasoning but does not encompass overall stages of development across a person's lifespan.

### Conclusion

Based on the analysis, the correct answer is:

**Erik Erikson**
